change white space with regular expression in python

I need to change white space to a character, but only if there are two or more white spaces and there is only one I want to keep it.

An example of text is:
142526 0x8520003 2 2022-10-20 The interface status changes. (ifName=Gig.

I need:
142526;0x8520003;2;2022-10-20 The interface status changes. (ifName=Gig.

I use:

';'.join(headers.split())

but change one space white also. Thanks!!

>Solution :

Use re.split() to match more than one space.

import re

new_headers = ';'.join(re.split(r'\s{2,}', headers)

\s matches whitespace, and {2,} means to match 2 or more of them in a row.
