Python format Integer into fixed length strings

Question

I want to generate a string based on an int along with zeros. And the length should always be of 5 not more then that nor less.

For example:

Consider a Integer: 1
Formatted String : 00001

Consider a Integer: 12
Formatted String : 00012

Consider a Integer: 110
Formatted String : 00110

Consider a Integer: 1111
Formatted String : 01111

Consider a Integer: 11111
Formatted String : 11111

Use the format() function or the str.format() method to format integers with zero-padding:

print format(integervalue, '05d')
print 'Formatted String : {0:05d}'.format(integervalue)

See the Format Specification Mini-Language; the leading 0 in the format signifies 0-padding, the 5 is the minimal field width; any number shorter than that is padded to the full width.

Demo:

>>> format(110, '05d')
'00110'
>>> 'Formatted String : {0:05d}'.format(12)
'Formatted String : 00012'
