Operators in Python

To know the bitwise operation, you can read here.

1 . Arithmetic operators.

These operators are used to perform mathematical operations.

Operator	Name	Example
+	Addition	3 + 2 = 5
–	Subtraction	3 – 2 = 1
*	Multiplication	3 * 2 = 6
/	Division	3 / 2 = 1.5
%	Modulus	3 % 2 = 1
**	Exponentiation	3 ** 2 = 9
//	Floor Division	3 // 2 = 1

2. Assignment Operators

These operators are used to assign values to variables. It works from right to left.

Operator	Example
=	x = 5 (Assigning value 5 to x)
+=	x += 3 or x = x +3
-=	x -= 5 or x = x – 5
*=	x *= 5 or x = x * 5
/=	x /= 5 or x = x / 5
%=	x %= 5 or x = x % 5
//=	x //= 5 or x = x // 5
**=	x **= 5 or x = x ** 5
&=	x &= 5 or x = x & 5
|=	x |=5 or x = x | 5
^=	x ^= 5 or x = x ^ 5
>>=	x >>= 3 or x = x >> 5
<<=	x <<= 5 or x = x << 5

3. Comparison Operator

Comparison operators are used to comparing two values.

Operator	Name	Example	Description
==	Equal	x == y	Return True if both the operands have the same value.
!=	Not Equal	x != y	Return True if both the operand have different values.
>	Greater than	x > y	Return True if the value of x is greater than the value of y.
<	Less than	x < y	Return True if the value of x is less than value of y.
>=	Greater than or equal to	x >= y	Return True if the value of x is greater than or the same as the value of y.
<=	Less than or equal to	x <= y	Return True if the value of x is lesser than or the same as the value of y.

4. Logical Operator

Logical operator are used to combine conditional statements like if else, elif.

Operator	Example	Description
and	x < 5 and x > 2	Returns True if both statements are true
or	x < 5 or x < 4	Returns True if any one of the statements is true.
not	not(x < 5 and x < 10)	Reverse the result, returns False if the result is true.

5. Membership Operators

Membership operators are used to test if a sequence is presented in an object.

Operator	Example	Description
in	x in y	Return True if a sequence with the specified value is present in the object.
not in	x not in y	Returns True if a sequence with the specified value is not present in the object

6. Bitwise operators

Operator	Name	Description
&	AND	Set each bit to 1 if both bits are 1
|	OR	Sets each bit to 1 if any one of the two bits is 1
^	XOR	Sets each bit to 1 if only two of its bits is 1
~	NOT	Inverse all the bits
<<	Zero Fill Left Shift	Shift left by pushing zeros in from right and let the leftmost bits fall off
>>	Signed right shift	Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off

7. Identity Operators

Identity operator is used to compare to object. It will check whether they are actually the same object having the same memory location.

Operator	Example	Description
is	x is y	Returns True if both x and y having same memory location
is not	x is not y	Returns True if both x and y have at different memory location
