Regex incorrect for huge numbers

[droidscout]

Hi,

I just found out using the range-regex module in pyton is not working to generate regular expressions when dealing with timestamps.
Let's say I want to generate a regex for values from 1420066800 to 1420153199 (unix timestamps) I get the regex: 1420[0-1][6-5][6-3][8-1]\\d{2} which apparently is wrong.
Using he "re" module in python together with the above regex throws an exception with message: "bad character range".
It would make sense to switch the numbers in a range if the left one is bigger than the right one.

Is there a way to get rid of this bug and update the module?

Thank you in advance.

Everybody who encounters the same problem, change the function: range_to_pattern to the following:

def range_to_pattern(start, stop):
    pattern = ''
    any_digit_count = 0

    for start_digit, stop_digit in zip(str(start), str(stop)):
        if start_digit == stop_digit:
            pattern += start_digit
        elif start_digit != '0' or stop_digit != '9':
            if start_digit > stop_digit:
                pattern += '[{}-{}]'.format(stop_digit, start_digit)
            else:
                pattern += '[{}-{}]'.format(start_digit, stop_digit)
        else:
            any_digit_count += 1

    if any_digit_count:
        pattern += r'\d'

    if any_digit_count > 1:
        pattern += '{{{}}}'.format(any_digit_count)

    return pattern
