Python Operators

Python Operators in general are used to perform operations on values and variables. These are standard symbols used for the purpose of logical and arithmetic operations. In this article, we will look into different types of Python operators.

Arithmetic Operators
Arithmetic operators are used to performing mathematical operations like addition, subtraction, multiplication, and division.

Operator Description Syntax
+ Addition: adds two operands x + y
– Subtraction: subtracts two operands x – y
* Multiplication: multiplies two operands x * y
/ Division (float): divides the first operand by the second x / y
// Division (floor): divides the first operand by the second x // y
% Modulus: returns the remainder when the first operand is divided by the second x % y
** Power: Returns first raised to power second x ** y

Comparison Operators
Comparison of Relational operators compares the values. It either returns True or False according to the condition.



Logical Operators
Logical operators perform Logical AND, Logical OR, and Logical NOT operations. It is used to combine conditional statements.

Operator Description Syntax
and Logical AND: True if both the operands are true x and y
or Logical OR: True if either of the operands is true x or y
not Logical NOT: True if the operand is false not x

Bitwise Operators
Bitwise operators act on bits and perform the bit-by-bit operations. These are used to operate on binary numbers.

Operator Description Syntax
& Bitwise AND x & y
| Bitwise OR x | y
~ Bitwise NOT ~x
^ Bitwise XOR x ^ y


Assignment Operators
Assignment operators are used to assigning values to the variables.
Operator Description Syntax
= Assign value of right side of expression to left side operand x = y + z
+= Add AND: Add right-side operand with left side operand and then assign to left operand a+=b a=a+b
-= Subtract AND: Subtract right operand from left operand and then assign to left operand a-=b a=a-b
*= Multiply AND: Multiply right operand with left operand and then assign to left operand a*=b a=a*b
/= Divide AND: Divide left operand with right operand and then assign to left operand a/=b a=a/b
%= Modulus AND: Takes modulus using left and right operands and assign the result to left operand a%=b a=a%b
//= Divide(floor) AND: Divide left operand with right operand and then assign the value(floor) to left operand a//=b a=a//b
**= Exponent AND: Calculate exponent(raise power) value using operands and assign value to left operand a**=b a=a**b
&= Performs Bitwise AND on operands and assign value to left operand a&=b a=a&b
|= Performs Bitwise OR on operands and assign value to left operand a|=b a=a|b
^= Performs Bitwise xOR on operands and assign value to left operand a^=b a=a^b

Identity Operators
is and is not are the identity operators both are used to check if two values are located on the same part of the memory. Two variables that are equal do not imply that they are identical.

is True if the operands are identical
is not True if the operands are not identical

Membership Operators
in and not in are the membership operators; used to test whether a value or variable is in a sequence.

in True if value is found in the sequence
not in True if value is not found in the sequence
