Python Operators
Python operators are used to perform operations on variables and values.
Python operators are as follow:
  • Arithmetic operators
  • Assignment operators
  • Comparison operators
  • Logical operators
  • Identity operators
  • Membership operators
  • Bitwise operators

Arithmetic operators

Operator
Name
Example
+
Addition
2 + 2
-
Subtraction
2 - 2
*
Multiplication
2 * 2
/
Division
2 / 2
%
Modulus
5 % 2
**
Exponentiation
2 ** 2
//
Floor division
2 // 2

Python Assignment Operators

Assignment operators are used to assign values to variables
Operator
Example
Same As
=
x = 2
x = 2
+=
x += 2
x = x + 2
-=
x -= 2
x = x - 2
*=
x *= 2
x = x * 2
/=
x /= 2
x = x / 2
%=
x %= 2
x = x % 2
//=
x //= 2
x = x // 2
**=
x **= 2
x = x ** 2
&=
x &= 2
x = x & 2
|=
x |= 2
x = x | 2
^=
x ^= 2
x = x ^ 2
>>=
x >>= 2
x = x >> 2
<<=
x <<= 2
x = x << 2

Python Comparison Operators

Comparison operators are used to compare two values
Operator
Name
Example
==
Equal
2 == 2
!=
Not equal
2 != 3
>
Greater than
2 > 1
<
Less than
2 < 3
>=
Greater than or equal to
2 >= 3
<=
Less than or equal to
2 <= 1

Python Logical Operators

Logical operators are used to combine conditional statements
Operator
Description
Example
and
Returns True if both statements are true
x < 5 and x < 10
or
Returns True if one of the statements is true
x < 5 or x < 4
not
Reverse the result, returns False if the result is true
not(x < 5 and x < 10)
​

Python Identity Operators

Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location
Operator
Description
Example
is
Returns True if both variables are the same object
x is y
is not
Returns True if both variables are not the same object
x is not y

Python Membership Operators

Membership operators are used to test if a sequence is presented in an object
Operator
Description
Example
in
Returns True if a sequence with the specified value is present in the object
x in y
not in
Returns True if a sequence with the specified value is not present in the object
x not in y

Python Bitwise Operators

Bitwise operators are used to compare (binary) numbers:
Operator
Name
Description
&
AND
Sets each bit to 1 if both bits are 1
|
OR
Sets each bit to 1 if one of two bits is 1
^
XOR
Sets each bit to 1 if only one of two bits is 1
~
NOT
Inverts all the bits
<<
Zero fill left shift
Shift left by pushing zeros in from the 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
