regex problem

[Odd-R.]

Input is a string of four digit sequences, possibly
separated by a -, for instance like this

"1234,2222-8888,4567,"

My regular expression is like this:

rx1=re.compile(r"""\A(\b\d\d\d\d,|\b\d\d\d\d-\d\d\d\d,)*\Z""")

When running rx1.findall("1234,2222-8888,4567,")

I only get the last match as the result. Isn't
findall suppose to return all the matches?

Thanks in advance.
