Consider re.findall(r'.{0,2}', 'abcde').

It finds 'ab', then continues where it left off to find 'cd', then 'e'.

It can also find ''; re.match(r'.*', '') does match, after all.

It could, in fact, an infinite number of ''.

And what about re.match(r'()*', '')?

What should it do? Run forever? Raise an exception?

At some point you have to make a decision as to what should happen, and the general consensus has been to match once.
