What's the best way to find all possible combinations of a numeric string in Python and compare them with a given string?

i’ve no idea how to resolve my problem. i ve a string like ‘0.0.0’ and i need to find all possible combinination, like ‘0.0.1’, ‘0.0.2’……. ‘9.9.9’ then compare with another string if is bigger or no.
no i’ve code like this

K = 1

    res = []
    for ele in version_string:

        if ele.isdigit():
            res.append(str(int(ele) + K))
            version_string = res
            version_string = ''.join(version_string)
        else:
            res.append(ele)

    print(str(version_string))

output

0.0
1.1
2.2
3.3
4.4
5.5
6.6

this code only increment every number by one but i need all combination.

thanks

>Solution :

import itertools

for numstr in ('.'.join(map(str, p)) for p in itertools.product(range(10), repeat=3)):
    print(numstr)
