Python Operators: Arithmetic, Assignment, Comparison, Logical, Identity, Membership, Bitwise
Operators are special symbols that perform some operation on operands and returns the result. For example, 5 + 6 is an expression where + is an operator that performs arithmetic add operation on numeric left operand 5 and the right side operand 6 and returns a sum of two operands as a result.
Python includes the operator module that includes underlying methods for each operator. For example, the + operator calls the operator.add(a,b) method.
Above, expression 5 + 6 is equivalent to the expression operator.add(5, 6) and operator.__add__(5, 6) . Many function names are those used for special methods, without the double underscores (dunder methods). For backward compatibility, many of these have functions with the double underscores kept.
Python includes the following categories of operators:
Arithmetic Operators
Assignment operators, comparison operators, logical operators, identity operators, membership test operators, bitwise operators.
Arithmetic operators perform the common mathematical operation on the numeric operands.
The arithmetic operators return the type of result depends on the type of operands, as below.
- If either operand is a complex number, the result is converted to complex;
- If either operand is a floating point number, the result is converted to floating point;
- If both operands are integers, then the result is an integer and no conversion is needed.
The following table lists all the arithmetic operators in Python:
| Operation | Operator | Function | Example in Python Shell |
|---|---|---|---|
| Sum of two operands | + | operator.add(a,b) | |
| Left operand minus right operand | - | operator.sub(a,b) | |
| * | operator.mul(a,b) | ||
| Left operand raised to the power of right | ** | operator.pow(a,b) | |
| / | operator.truediv(a,b) | ||
| equivilant to | // | operator.floordiv(a,b) | |
| Reminder of | % | operator.mod(a, b) |
The assignment operators are used to assign values to variables. The following table lists all the arithmetic operators in Python:
| Operator | Function | Example in Python Shell |
|---|---|---|
| = | ||
| += | operator.iadd(a,b) | |
| -= | operator.isub(a,b) | |
| *= | operator.imul(a,b) | |
| /= | operator.itruediv(a,b) | |
| //= | operator.ifloordiv(a,b) | |
| %= | operator.imod(a, b) | |
| &= | operator.iand(a, b) | |
| |= | operator.ior(a, b) | |
| ^= | operator.ixor(a, b) | |
| >>= | operator.irshift(a, b) | |
| <<= | operator.ilshift(a, b) |
The comparison operators compare two operands and return a boolean either True or False. The following table lists comparison operators in Python.
| Operator | Function | Description | Example in Python Shell |
|---|---|---|---|
| > | operator.gt(a,b) | True if the left operand is higher than the right one | |
| < | operator.lt(a,b) | True if the left operand is lower than right one | |
| == | operator.eq(a,b) | True if the operands are equal | |
| != | operator.ne(a,b) | True if the operands are not equal | |
| >= | operator.ge(a,b) | True if the left operand is higher than or equal to the right one | |
| <= | operator.le(a,b) | True if the left operand is lower than or equal to the right one |
The logical operators are used to combine two boolean expressions. The logical operations are generally applicable to all objects, and support truth tests, identity tests, and boolean operations.
| Operator | Description | Example |
|---|---|---|
| and | True if both are true | |
| or | True if at least one is true | |
| not | Returns True if an expression evalutes to false and vice-versa |
The identity operators check whether the two objects have the same id value e.i. both the objects point to the same memory location.
| Operator | Function | Description | Example in Python Shell |
|---|---|---|---|
| is | operator.is_(a,b) | True if both are true | |
| is not | operator.is_not(a,b) | True if at least one is true |
The membership test operators in and not in test whether the sequence has a given item or not. For the string and bytes types, x in y is True if and only if x is a substring of y .
| Operator | Function | Description | Example in Python Shell |
|---|---|---|---|
| in | operator.contains(a,b) | Returns True if the sequence contains the specified item else returns False. | |
| not in | not operator.contains(a,b) | Returns True if the sequence does not contains the specified item, else returns False. |
Bitwise operators perform operations on binary operands.
| Operator | Function | Description | Example in Python Shell |
|---|---|---|---|
| & | operator.and_(a,b) | Sets each bit to 1 if both bits are 1. | |
| | | operator.or_(a,b) | Sets each bit to 1 if one of two bits is 1. | |
| ^ | operator.xor(a,b) | Sets each bit to 1 if only one of two bits is 1. | |
| ~ | operator.invert(a) | Inverts all the bits. | |
| << | operator.lshift(a,b) | Shift left by pushing zeros in from the right and let the leftmost bits fall off. | |
| >> | operator.rshift(a,b) | Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off. |

Java Assignment Operators with Examples
Operators constitute the basic building block of any programming language. Java too provides many types of operators which can be used according to the need to perform various calculations and functions, be it logical, arithmetic, relational, etc. They are classified based on the functionality they provide.
Types of Operators:
- Arithmetic Operators
- Unary Operators
- Assignment Operator
- Relational Operators
- Logical Operators
- Ternary Operator
- Bitwise Operators
- Shift Operators
This article explains all that one needs to know regarding Assignment Operators.
Assignment Operators
These operators are used to assign values to a variable. The left side operand of the assignment operator is a variable, and the right side operand of the assignment operator is a value. The value on the right side must be of the same data type of the operand on the left side. Otherwise, the compiler will raise an error. This means that the assignment operators have right to left associativity, i.e., the value given on the right-hand side of the operator is assigned to the variable on the left. Therefore, the right-hand side value must be declared before using it or should be a constant. The general format of the assignment operator is,
Types of Assignment Operators in Java
The Assignment Operator is generally of two types. They are:
1. Simple Assignment Operator: The Simple Assignment Operator is used with the “=” sign where the left side consists of the operand and the right side consists of a value. The value of the right side must be of the same data type that has been defined on the left side.
2. Compound Assignment Operator: The Compound Operator is used where +,-,*, and / is used along with the = operator.
Let’s look at each of the assignment operators and how they operate:
1. (=) operator:
This is the most straightforward assignment operator, which is used to assign the value on the right to the variable on the left. This is the basic definition of an assignment operator and how it functions.
Syntax:
Example:
2. (+=) operator:
This operator is a compound of ‘+’ and ‘=’ operators. It operates by adding the current value of the variable on the left to the value on the right and then assigning the result to the operand on the left.
Note: The compound assignment operator in Java performs implicit type casting. Let’s consider a scenario where x is an int variable with a value of 5. int x = 5; If you want to add the double value 4.5 to the integer variable x and print its value, there are two methods to achieve this: Method 1: x = x + 4.5 Method 2: x += 4.5 As per the previous example, you might think both of them are equal. But in reality, Method 1 will throw a runtime error stating the “i ncompatible types: possible lossy conversion from double to int “, Method 2 will run without any error and prints 9 as output.
Reason for the Above Calculation
Method 1 will result in a runtime error stating “incompatible types: possible lossy conversion from double to int.” The reason is that the addition of an int and a double results in a double value. Assigning this double value back to the int variable x requires an explicit type casting because it may result in a loss of precision. Without the explicit cast, the compiler throws an error. Method 2 will run without any error and print the value 9 as output. The compound assignment operator += performs an implicit type conversion, also known as an automatic narrowing primitive conversion from double to int . It is equivalent to x = (int) (x + 4.5) , where the result of the addition is explicitly cast to an int . The fractional part of the double value is truncated, and the resulting int value is assigned back to x . It is advisable to use Method 2 ( x += 4.5 ) to avoid runtime errors and to obtain the desired output.
Same automatic narrowing primitive conversion is applicable for other compound assignment operators as well, including -= , *= , /= , and %= .
3. (-=) operator:
This operator is a compound of ‘-‘ and ‘=’ operators. It operates by subtracting the variable’s value on the right from the current value of the variable on the left and then assigning the result to the operand on the left.
4. (*=) operator:
This operator is a compound of ‘*’ and ‘=’ operators. It operates by multiplying the current value of the variable on the left to the value on the right and then assigning the result to the operand on the left.
5. (/=) operator:
This operator is a compound of ‘/’ and ‘=’ operators. It operates by dividing the current value of the variable on the left by the value on the right and then assigning the quotient to the operand on the left.
6. (%=) operator:
This operator is a compound of ‘%’ and ‘=’ operators. It operates by dividing the current value of the variable on the left by the value on the right and then assigning the remainder to the operand on the left.

C Functions
C structures, c reference, c operators.
Operators are used to perform operations on variables and values.
In the example below, we use the + operator to add together two values:
Although the + operator is often used to add together two values, like in the example above, it can also be used to add together a variable and a value, or a variable and another variable:
C divides the operators into the following groups:
- Arithmetic operators
- Assignment operators
- Comparison operators
- Logical operators
- Bitwise operators
Arithmetic Operators
Arithmetic operators are used to perform common mathematical operations.
| Operator | Name | Description | Example | Try it |
|---|---|---|---|---|
| + | Addition | Adds together two values | x + y | |
| - | Subtraction | Subtracts one value from another | x - y | |
| * | Multiplication | Multiplies two values | x * y | |
| / | Division | Divides one value by another | x / y | |
| % | Modulus | Returns the division remainder | x % y | |
| ++ | Increment | Increases the value of a variable by 1 | ++x | |
| -- | Decrement | Decreases the value of a variable by 1 | --x |
Assignment Operators
Assignment operators are used to assign values to variables.
In the example below, we use the assignment operator ( = ) to assign the value 10 to a variable called x :
The addition assignment operator ( += ) adds a value to a variable:
A list of all assignment operators:
| Operator | Example | Same As | Try it |
|---|---|---|---|
| = | x = 5 | x = 5 | |
| += | x += 3 | x = x + 3 | |
| -= | x -= 3 | x = x - 3 | |
| *= | x *= 3 | x = x * 3 | |
| /= | x /= 3 | x = x / 3 | |
| %= | x %= 3 | x = x % 3 | |
| &= | x &= 3 | x = x & 3 | |
| |= | x |= 3 | x = x | 3 | |
| ^= | x ^= 3 | x = x ^ 3 | |
| >>= | x >>= 3 | x = x >> 3 | |
| <<= | x <<= 3 | x = x << 3 |
Comparison Operators
Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions.
The return value of a comparison is either 1 or 0 , which means true ( 1 ) or false ( 0 ). These values are known as Boolean values , and you will learn more about them in the Booleans and If..Else chapter.
Comparison operators are used to compare two values.
Note: The return value of a comparison is either true ( 1 ) or false ( 0 ).
In the following example, we use the greater than operator ( > ) to find out if 5 is greater than 3:
A list of all comparison operators:
| Operator | Name | Example | Description | Try it |
|---|---|---|---|---|
| == | Equal to | x == y | Returns 1 if the values are equal | |
| != | Not equal | x != y | Returns 1 if the values are not equal | |
| > | Greater than | x > y | Returns 1 if the first value is greater than the second value | |
| < | Less than | x < y | Returns 1 if the first value is less than the second value | |
| >= | Greater than or equal to | x >= y | Returns 1 if the first value is greater than, or equal to, the second value | |
| <= | Less than or equal to | x <= y | Returns 1 if the first value is less than, or equal to, the second value |
Logical Operators
You can also test for true or false values with logical operators.
Logical operators are used to determine the logic between variables or values, by combining multiple conditions:
| Operator | Name | Example | Description | Try it |
|---|---|---|---|---|
| && | AND | x < 5 && x < 10 | Returns 1 if both statements are true | |
| || | OR | x < 5 || x < 4 | Returns 1 if one of the statements is true | |
| ! | NOT | !(x < 5 && x < 10) | Reverse the result, returns 0 if the result is 1 |

Go Operators
Golang tutorial index.
Every programming language comes with operators as its base element. None of the functionalities, operations, and calculations can be completed without these. This tutorial will teach you what operators are and the different types of operators in Go programming.
Arithmetic Operators
Comparison operators, assignment operators, logical operators, bitwise operators, address operators, pointer operators, what are operators in go.
Operators are operating symbols in the Go programming language that instruct the compiler to perform specific operations on operands (variable or constant values) to produce a final result or output. In the following sections, we'll discuss the many different types of operators supported by the Go language.
In Go, there are several arithmetic operators that allow you to perform basic mathematical operations, including addition, subtraction, multiplication, and division. Go has the following arithmetic operators:
| Operator | Description |
|---|---|
| Addition operator. Adds two operands. | |
| Subtraction operator. Subtracts the second operand from the first. | |
| Multiplication operator. Multiplies the two operands. | |
| Division operator. Divides the first operand by the second. | |
| Modulus operator. Returns the remainder when the first operand is divided by the second. |
Here's an example of using Arithmetic Operators in Go:
Comparison operators are used to evaluate whether the values of two operands are equal or whether one value is greater than or less than the other. If the comparison is true , the result of the operator will be a true boolean value. The result will be a false boolean value if the comparison is false . Go has the following comparison operators:
| Operator | Description |
|---|---|
| Equal to operator. Returns if the value of operands are equal, otherwise. | |
| Not equal to operator. Returns if the value of operands operands are not equal, otherwise. | |
| Greater than operator. Returns if the value of the first operand is greater than the second, otherwise. | |
| Less than operator. Returns if the value of the first operand is less than the second, otherwise. | |
| Greater than or equal to operator. Returns if the value of the first operand is greater than or equal to the second, otherwise. | |
| Less than or equal to operator. Returns if the value of the first operand is less than or equal to the second, otherwise. |
Here's an example of using Comparison Operators in Go:
Go has several assignment operators that can be used to assign a value to a variable. These operators include:
| Operator | Description |
|---|---|
| Simple assignment operator. Assigns the value on the right side to the variable on the left side | |
| Addition assignment operator. Adds the value on the right side to the variable on the left side and assigns the result to the variable. | |
| Subtraction assignment operator. Subtracts the value on the right side from the variable on the left side and assigns the result to the variable. | |
| Multiplication assignment operator. Multiplies the value on the right side by the variable on the left side and assigns the result to the variable. | |
| Division assignment operator. Divides the variable on the left side by the value on the right side and assigns the result to the variable. | |
| Modulus assignment operator. Calculates the remainder when the variable on the left side is divided by the value on the right side and assigns the result to the variable. |
Here's an example of using Assignment Operators in Go:
Go has three logical operators that can be used to perform logical operations on boolean values. These operators include:
| Operator | Description |
|---|---|
| Logical AND operator. Returns if both operands are , otherwise. | |
| Logical OR operator. Returns if either operand is , otherwise. | |
| Logical NOT operator. Inverts the boolean value of the operand. If the operand is , the NOT operator returns . If the operand is , the NOT operator returns . |
Here's an example of using Logical Operators in Go:
Go also has several bitwise operators that can be used to perform bitwise operations on integer values. These operators include:
| Operator | Description |
|---|---|
| Bitwise AND operator. Performs a bitwise AND operation on the two operands. | |
| Bitwise OR operator. Performs a bitwise OR operation on the two operands. | |
| Bitwise XOR operator. Performs a bitwise XOR operation on the two operands. | |
| Bit clear operator. Performs a bit clear operation on the two operands. | |
| Left shift operator. Shifts the bits of the left operand to the left by the number of positions specified by the right operand. | |
| Right shift operator. Shifts the bits of the left operand to the right by the number of positions specified by the right operand. |
Here's an example of using Bitwise Operators in Go:
Go has an address operator, & , that can be used to obtain the memory address of a variable. The & operator generates a pointer to the variable.
The code above will print the memory address of the variable x .
Go has a * operator that is used in conjunction with pointers. The * operator is used to dereference a pointer or access the value stored at the memory address pointed to by the pointer.
The code above will print the value of x , which is 10 .

PHP Assignment Operators. PHP assignment operators applied to assign the result of an expression to a variable. = is a fundamental assignment operator in PHP. It means that the left operand gets set to the value of the assignment expression on the right. Operator.
Java Comparison Operators. Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions. The return value of a comparison is either true or false. These values are known as Boolean values, and you will learn more about them in the Booleans and If ...
These are examples of assignment operators. Essentially, they both perform the arithmetic operation on a variable, and assign its result to that variable, in a single operation. They're equivalent to doing it in two steps, for the most part: int a = 23; int b = 2; a += b; // addition - same as `a = a + b`. a -= b; // subtraction.
