Python operators:

By using operators we can update or compare values or identities of variables.

Operation	Operator	Sample	Output
Addition	+	a=4 b=5 print(a+b)	9
Subtraction	-	print(a-b)	-1
Multiplication	*	print(a*b)	20
Division	/	print(a/b)	0.8
Modulus	%	a=40 b=9 print(a%b)	4
Exponentiation	**	a=3 b=4 print(a**b)	81
Floor division	//	a=29 b=5 print(a//b)	5

Assignment Operators

We can assign or update value of a variable by using assignment operators

Operator	Syntax	Equivalent	Sample	Output
=	x=5	x=5	x=5 print(x)	5
+=	x += 5	x = x + 5	x=4 x += 5 print(x)	9
-=	x -= 5	x = x - 5	x=4 x -= 5 print(x)	-1
*=	x *= 5	x = x * 5	x=4 x *= 5 print(x)	20
/=	x /= 5	x = x / 5	x=4 x /= 5 print(x)	0.8
%=	x %= 5	x = x % 5	x=29 x %= 5 print(x)	4
//=	x //= 5	x = x // 5	x=29 x //= 5 print(x)	5
**=	x **= 3	x = x ** 3	x=5 x **= 3 print(x)	125

&=	x &= 5	x = x & 5	x=68 x &=5 print(x)	4
\|=	x \|= 5	x = x \| 5	x=68 x \|=5 print(x)	69
^=	x ^= 5	x = x ^ 5	x=68 x ^=5 print(x)	65
>>=	x >>= 5	x = x >> 5	x=68 x >>= 5 print(x)	2
<<=	x <<= 5	x = x << 5	x=68 x <<= 5 print(x)	2

Comparison Operators

We can compare two variable values by using comparison operators. Output of these comparison operator is always Boolean ( True or False )

Operation	Operator	Sample	Output
Equal	==	a=4 b=5 print(a == b)	False
Not Equal	!=	a=4 b=5 print(a != b)	True
Greater than	>	a=4 b=5 print(a > b)	False
Less than	<	a=4 b=5 print(a < b)	True
Greater than or equal to	>=	a=4 b=5 print(a>=b)	False
Less than or equal to	<=	a=4 b=5 print(a<=b)	True

Logical Operators

Operator	Description	Sample	Output
and	True if both left and right side are True	a=5 b=15 print(a>10 and b<25)	False
or	True if any one of left or right side are True	a=5 b=15 print(a>10 or b<25)	True
not	Reverse the output. True if output is False , vice versa	a=5 print( not(a>10))	True
