Python Operator

Operator are used to perform operations on variables and value.

• Arithmetic Operators
• Assignment Operators
• Comparison Operator
• Logical Operator
• Identity Operator
• Bitwise Operator
• Membership Operator

Python Arithmetic Operators

It is used with numeric values to performs mathematical Operations.

Operator Name Example
- Subtracation X-Y
* Multiplication X*Y
/ Division X/Y
% Modulus X%Y
// Floor Division X//Y
** Exponentiation X**Y

Python Assignment Operators

Assignment operators are used to assign values to variables:

Operator Name Example
= x=5 x=5
+= x+=6 x=x+6
-= x-=7 x=x-7
*= x*=4 x=x*4
/= x/=3 x=x/3
%= x%=3 x=x%3
//= x//=6 x=x//6
**= x**=6 x=x**6
&= x&=7 x=x&7
I= xI=7 x=xI7
^= x ^=5 x=x^5
>>= x>>=6 x=x>>6
<<= x<<=5 x=x<<5

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
>= 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 Return true if both statement true X<5 and X<10
or Return true if one of the statement is true X<5 or X<3
not Reverse the result, returns False if the result is true Not(x < 6 and x < 10)

Python Identity Operators

It is used to compare the object,not if they are equal ,but they are same object and allocated with the same memory location:-

Operator Description Example
is Return 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

Python membership operators test for membership in a sequence, such as strings, lists, or tuples.

Operator Description Example
in Return true if finds a variable in the specified sequence. X in Y
not in Return true if does not finds a variable in the specified sequence X not in Y

Python Bitwise Operators

Bitwise operator works on bits and performs bit by bit operation:-

Operator Name Description Example
& And Operator copies a bit to the result if it exists in both operands (a & b) (means 0000 1100)
| OR It copies a bit if it exists in either operand. (a | b) = 61 (means 0011 1101)
^ XOR It copies the bit if it is set in one operand but not both. (a ^ b) = 49 (means 0011 0001)
~ NOT Inverts all the bits (~a ) = -61 (means 1100 0011 in 2's complement form due to a signed binary number.
>> Binary Right Shift The left operands value is moved right by the number of bits specified by the right operand. a << 2 = 240 (means 1111 0000)
<< Binary Left Shift Shift left by pushing zeros in from the right and let the leftmost bits fall off a >> 2 = 15 (means 0000 1111)
