Python Operators

Arithmetic Operators

Name	Operator	Example
Addition	+	a + b
Subtraction	-	a - b
Multiplication	*	a * b
Division	/	a / b
Exponential	**	a ** b
Modulus	%	a % b
Floor Division	//	a // b

Assignment Operators

Name	Evaluated As
=	a = b
+=	a += b    or    a = a + b
-=	a -= b    or    a = a - b
*=	a *= b    or    a = a * b
**=	a **= b    or    a = a ** b
/=	a /= b    or    a = a / b
//=	a //= b    or    a = a // b
%=	a %= b    or    a = a % b
&=	a &= b    or    a = a & b
|=	a |= b    or    a = a | b
^=	a ^= b    or    a = a ^ b
>>=	a >>= b    or    a = a >> b
<<=	a <<= b    or    a = a << b

Bitwise Operators

Name	Operator	Example
Bitwise AND	&	a & b
Bitwise OR	|	a | b
Bitwise NOT	~	~a
Bitwise XOR	^	a ^ b
Bitwise right shift	>>	a >> b
Bitwise left shift	<<	a << b

Comparison Operators

Name	Operator	Example
Equal	==	a == b
Not Equal	!=	a != b
Less Than	<	a < b
Greater Than	>	a > b
Less Than or Equal to	<=	a <= b
Greater Than or Equal to	>=	a >= b

Identity Operators

Name	Example	Evaluated As
is	a is b	Returns True if a and b are same
is not	a is not b	Returns True if a and b are not same

Logical Operators

Name	Operator	Example
AND	and	a and b
OR	or	a or b
NOT	not	not(a and b)

Membership Operators

Name	Example	Evaluated As
in	a in b	Returns True if a is present in given sequence or collection
not in	a not in b	Returns True if a is not present in given sequence or collection
