How to check if text has certain format?

Question

How to check if text/string has (number:number-number) format in Python?

An example is (7:10-9)

I think I need to use Regex?

Answer 1

Yes, that would be the easiest. Example:

In [1]: import re

In [2]: re.match('\(\d+:\d+-\d+\)', '(7:10-9)')
Out[2]: <_sre.SRE_Match at 0x24655e0>

In [3]: re.match('\(\d+:\d+-\d+\)', '(7)')

In [4]: 

As a function:

def match(s):
    return bool(re.match('\(\d+:\d+-\d+\)', s))

Don't forget to look through the docs.
