It doesn't meet the OP's requirement that the number
can start with 0. Also, the method the OP asks about
returns a list of unique numbers, so no number can
be duplicated. He can get 02468 but not 13345.

Now, IF it's ok to have an arbitrary number of leading
0s, he can do this:

>>> str(random.randint(0,99999)).zfill(5)
'00089'
>>> str(random.randint(0,99999)).zfill(5)
'63782'
>>> str(random.randint(0,99999)).zfill(5)
'63613'
>>> str(random.randint(0,99999)).zfill(5)
'22315'
