Python's str.zfill(~) method returns a copy of the source string left filled with zeros (0) up to the provided length.

Parameters

1. width | number

The length of the returned string including the left filled zeros.

Return value

A copy of the source string with '0' filled to the left.

Examples

Basic usage

To return a copy of 'Hello' left filled with zeros up to 7 characters:

x = 'Hello'
x.zfill(7)
'00Hello'

Width parameter

To return a copy of 'Hello' left filled with zeros up to 3 characters:

x = 'Hello'
x.zfill(3)
'Hello'

As the provided width of 3 was shorter than the length of the source string, we return the source string 'Hello'.
