Look at formatting strings in Python.

str.format() is the preferred way to do this if you are using Python >=2.6

>>> a=[1000, 200, 30]
>>> map("{0:05}".format, a)
['01000', '00200', '00030']

You can do it like this:

a = [1000,200,30]
b = ["%05d" % (i) for i in a]
print b

The number tells the width and the leading zero says that you want leading zeros.

map(lambda x:str(x).zfill(5),a)

>>> a=[1000,200,30]
>>> [str(e).zfill(5) for e in a]
['01000', '00200', '00030']

str.zfill
