Operator in Python पायथन में ऑपरेटर
Operators are used to perform operations on variables and values.

Python divides the operators in the following groups:
- Arithmetic operators
- Assignment operators
- Comparison operators
- Logical operators
- Identity operators
- Membership operators
- Bitwise operators
Python Arithmetic Operators
Arithmetic operators are used with numeric values to perform common
mathematical operations:
Operator Name
Example
+
Addition
x + y
-
Subtraction
x - y
*
Multiplication
x * y
/
Division
x / y
%
Modulus
x % y
**
Exponentiation x ** y
//
Floor division
x // y
Example :
print (3+3)
print (3-3)
print (3/3)
print (3*3)
print (7%3)
print (13//3)#the floor division // rounds the result down to the
nearest whole number
print (3**3) 'power'
Output

1.0

Python Assignment Operators
Assignment operators are used to assign values to variables:
Operator Example
Same As
=
x = 5 x = 5
+=
x += 3 x = x + 3
-=
x -= 3 x = x - 3
*=
x *= 3 x = x * 3
/=
x /= 3 x = x / 3
%=
x %= 3 x = x % 3
//=
x //= 3 x = x // 3
**=
x **= 3 x = x ** 3
&=
x &= 3 x = x & 3
|=
x |= 3 x = x | 3
^=
x ^= 3 x = x ^ 3
>>=
x >>= 3 x = x >>
3
<<=
x <<= 3 x = x << 3
Python Comparison Operators
Comparison operators are used to compare two values:
Operator Name
Example
==
Equal
x == y
!=
Not equal
x != y
>
Greater than
x > y
<
Less than
x < y
>=
Greater than or equal to x >= y
<=
Less than or equal to x <=
y
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
