Read the documentation of os module to find suitable command and use a loop and string formatting to do zero padded number:

print('%03i.txt' % 5)

Output:

005.txt

If you're using linux, this may be handled more simply with a bash script.

It`s simpel with python to,and this is a python forum.
@crishein14 save script in folder with files and run.

import os, glob

for numb,name in enumerate(glob.glob('*png')):
    os.rename(name, '{num:03d}.png'.format(num=numb))

[Lardmeister]

Meister snippsat's solution is easy, but be careful, it will rename any .png file in the directory. You might want to make sure that the name starts with an integer at least.

im only using pys60 .. Symbian ! Python says no module named glob :(

[snippsat]

Try.

import os

for numb,name in enumerate(os.listdir(".")):
    if name.endswith(".png"):
        os.rename(name, '{num:03d}.png'.format(num=numb))

Or.

glob, fnmatch
Standard Python modules that are not part of PyS60 distribution, with slight modifications
so they work with PyS60.
Glob allows directory listing with wild cards, fnmatch is used by glob. Used by sync, btconsole.

[snippsat]

I think pyS60 use python 2.5.4,then you have to use old string formatting like this.
You should of course mention in first post that you use pyS60.

import os

for numb,name in enumerate(os.listdir(".")):
    if name.endswith(".png"):
        os.rename(name, '%03i.png' % numb)

thankyou so much for all of you .. im noob in python ! i want to learn more in python .. sorry for my bad english :)

[crishein14]

i try to run the code above .. python say's
for numb,name in enumerate(os.listdir("e:Py")):
NameError: name 'enumerate' is not defined

Implement it yourself

from __future__ import generators # does your python need this ?

def enumerate(iterable, start=0):
    i = start - 1
    for item in iterable:
        i += 1
        yield (i, item)

[snippsat]

You should uppgarde your pyS60 version if enumerate() not work.
enumerate() was new in python 2.3 in 2003.
It`s difficult to write/learn python if you cannot use features implemented last 10 years.

[M.S.]

the most widely used pys60 is v1.45 and is a port of python 2.2.2. the pys60 v1.9.7 that is a python 2.5 port that is less used.
for pys60 there are many modules for manipulating files and dirs, as an example I can suggest the pow_light fm module or fman module.there is also a shutil module for pys60.
