# Python Bitwise Left Shift Operator

## Left Shift Operator

Bitwise Left Shift Operator is used to push zero bits on the rightmost side and let the leftmost bits to overflow. This is also called Zero-Fill Left-Shift.

## Symbol

The symbol of bitwise Left Shift operator is `<<`.

## Syntax

The syntax to do bitwise Left Shift operation for the operands: `x` and `y`, is

``x << y``

This operation left shifts the bits in `x`, by `y` number of times.

## Example

The following is a simple example of how bitwise Left Shift operation is done for given two numbers.

``````x = 5
y = 2

#bit level
x = 00000101
x << 2 = 00010100

Therefore x << y = 20``````

In this following program, we take integer values in `x`, and `y`, and perform bitwise Left Shift operation `x << y`.

Python Program

``````x = 5
y = 2
output = x << y
print(f'{x}<<{y} = {output}')``````
Run

Output

``5<<2 = 20``
