Bitwise Operators

We can apply these operators bitwise.
These operators are applicable only for int and Boolean types.
By mistake if we are trying to apply for any other type then we will get Error.
Bitwise operators are;
- & (Bitwise and) ⇒ If both bits are 1 then only result is 1 otherwise result is 0.
- | (Bitwise or) ⇒ If atleast one bit is 1 then result is 1 otherwise result is 0.
- ^ (Bitwise xor) ⇒ If bits are different then only result is 1 otherwise result is 0.
- ~ (Bitwise complement) ⇒ bitwise complement operator i.e. 1 means 0 and 0 means 1 and it complement for total bits.
- << (Bitwise left shift)
- >> (Bitwise right shift)

Example

Python

print(4&5)
print(4|5)
print(4^5)
print(~5)
print(True & False)

Output

PowerShell

4
5
1
-6
False

Example

Python

print(10.5 & 5.6)

Output

PowerShell

TypeError: unsupported operand type(s) for &: 'float' and 'float'

Remark

The most significant bit acts as sign bit. 0 value represents +ve number where as 1 represents -ve value.
Positive numbers will be represented directly in the memory where as -ve numbers will be represented indirectly in 2’s complement form.

Operator	Description
&	If both bits are 1 then only result is 1 otherwise result is 0
\|	If atleast one bit is 1 then result is 1 otherwise result is 0
^	If bits are different then only result is 1 otherwise result is 0
~	bitwise complement operator i.e. 1 means 0 and 0 means 1
>>	Bitwise Left shift Operator
<<	Bitwise Right shift Operator

Bitwise Complement Operator (~)

We have to apply complement for total bits.

Example

Python

print(~5)

Output

PowerShell

-6

Shift Operators

There are two types of shift operators.

Left shift operator (<<)
Right shift operator (>>)

<< Left shift operator

Shift the digits from right to left.
After shifting the empty cells we have to fill with zero.

Example

Python

num1 = 10
print(bin(num1))

num1 = num1<<2
print(bin(num1))

Output

PowerShell

'0b1010'
'0b101000'

>>Right Shift operator

Shift the digits from left to right.
After shifting the empty cells we have to fill with sign bit.( 0 for +ve and 1 for -ve)

Example

Python

num1 = 10
print(bin(num1))

num1 = num1>>2
print(bin(num1))

Output

PowerShell

'0b1010'
'0b10'

Remark

We can apply bitwise operators for Boolean types also.

Python

print(True & False)
print(True | False)
print(True ^ False)
print(~True)
print(True>>2)

Output

PowerShell

False
True
True
-2
0
