It returns original length string if the width is less than string length.
Signature
Parameters
width : length of the string.
Return
It returns a string.
Let’s see some examples of zfill() method to understand it’s functionality.
Python String zfill() Method Example 1
Let’s see an example which has width greater than string length. It returns a new string containing 0 to the left and total length is equal to width.
Output:
0000000Zfill Example
Python String zfill() Method Example 2
Here, we are passing width less than the string length therefore it returns the original string without filling zeros to the left.
Output:
Zfill Example
Python String zfill() Method Example 3
This example describes the sign either + or – includes before the zero fills to the left of the string. See every value is filled after prefixing (+ or -) sign.
Output:
+000000100 -000000200 -0-Rohan--
