Python Operators


Python operators are the symbol that are used to perform some operation on single or multiple operands and produces a result.

There are following types of operators in Python:

  1. Arithmetic Operators
  2. Comparison (Relational) Operators
  3. Assignment Operators
  4. Logical Operators
  5. Bitwise Operators
  6. Membership Operators
  7. Identity Operators

Python Arithmetic Operators

Python Arithmetic operators are used to perform arithmetic/mathematical operations on the operands.

Operator Description Example
+ Addition 10 + 8 = 18
- Subtraction 10 – 8 = 2
* Multiplication 10 * 8 = 80
/ Division 10 / 8 = 1
% Modulus (remainder) 10 % 8 = 2
** Exponent 10**2 = 100
// Floor division -14/3 = -5


Python Relational Operators

Python comparison operator compares the two operands and return boolean true or false accordingly.

Operator Description Example
== Is equals to 10 == 5 (false)
!= Not equals to 10 != 5 (true)
> Greater than 10 > 10 (false)
>= Greater than or equals to 10 >= 10 (true)
< Less than 10 < 10 (false)
<= Less than or equals to 10 <= 10 (true)
<> Not equals to 10 <> 5 (true)

Python Assignment Operators

Python assignment operators are used to assign value to variables.

Operator Description Example
= Assign var a = 10; a = 5; Now a = 5
+= Add and assign var a = 10; a += 5; Now a = 15
-= Subtract and assign var a = 10; a -= 5; Now a = 5
*= Multiply and assign var a = 10; a *= 5; Now a = 50
/= Divide and assign var a = 10; a /= 5; Now a = 2
%= Modulus and assign var a = 10; a %= 5; Now a = 0
**= Exponent and assign var a = 10; a **= 2; Now a = 100
//= Floor Division and assign var a = 10; a //= 5; Now a = 2


Python Logical Operators

Python logical operators combine two or more conditions and return boolean true or false accordingly.

Operator Description Example
and Logical AND (5 == 10 and 10 ==10) = false
or Logical OR (5 == 10 or 10 ==10) = true
not Logical Not not (5 == 10) = true

Python Bitwise Operators

Python bitwise operators perform the bitwise operation on single or multiple operands and return the result.

Bit operators work on 32 bits numbers.

Operator Description Example
& Bitwise AND 5 == 10 & 20 == 20 (false)
| Bitwise OR 5 == 10 | 20 == 20 (true)
^ Bitwise XOR 5 == 10 ^ 20 == 20 (true)
~ Bitwise NOT (~5) = (-5)
<< Bitwise Left Shift (2 << 1) = 4
>> Bitwise Right Shift (2 >> 1) = 1

Python Membership Operators

Python membership operators are used to test for the membership of the value in a data structure. It returns true if the value is present in the data structure otherwise it returns false.

Operator Description Example
in tests for presence of the variable a in b; returns true if a is present in b
not in tests for absence of the variable a not in b; returns true if a is absent in b


Python Identity Operators

Python identity operators are used to compare the memory locations of 2 objects.

Operator Description Example
is compares for same reference at both sides a is b; returns true if id(a) and id(b) are equals
is not compares for different reference at both sides a is not b; returns true if id(a) and id(b) are not equals

Python Operator Precedence

The python operator precedence helps us to find which operator should be evaluated first. The operator precedence table is as follows:

Operator Description
** Exponent
~, +, - Negation, unary plus and minus
*, /, %, // Multiplication, divide, modulus and floor division
+, - Binary plus and minus
>>, << Right shift and left shift
& Binary And
^, | Binary Xor and Or
<, <=, >, >= Comparison operators
<>, ==, != Equality operators
=, +=, -=, *=, /=, %=, **=, //= Assignment operators
is, is not Identity operators
in, in not Membership operators
not and or Logical operators
