What re.findall returns

Question

Accepted Answer

re.findall() returns a plain Python list of all non-overlapping matches as strings, not Match objects. The pattern r'\d+' matches one or more digit characters, so it finds '42', '3', and '100' in order. The return type is always a list of strings (or a list of tuples when the pattern contains capturing groups). Because the values come back as strings, you need int() or float() if you plan to do arithmetic on them.
