The error gives something away (like any good error message should)
You're attempting to repeat something that may not exist. In
this case, it's the last question-mark. The item before it
(\d*)
could be empty, and thus have "nothing to repeat".
Simply removing the question-mark in question, making it
r'([^\d]*)(\d{1,3}\.\d{0,2})?(\d*)(\,\d{1,3}\.\d{0,2})?(\d*).*'
has the same effect as desired (AFAIU) without the error.
