>>> sample = "eat, drink; man, woman"
>>> sample.replace(";", ",")
'eat, drink, man, woman'
>>> sample
'eat, drink; man, woman'
Aha, Python doesn't replace in place, it creates a new string instead.

>>> sample = "eat+-drink+man-woman"
>>> sample.split("+-")
['eat', 'drink+man-woman']
>>> sample.split("+")
['eat', '-drink', 'man-woman']
Aha, Python interprets the complete split() argument as the delimiter, not
each of its characters.
Do you think you can combine these two findings to make your code work? You
will have to replace() first and then split().
