Thanks all for good advice. However this last expression
also matches the first four digits when the input is more
than four digits. To resolve this problem, I first do a
match of this,
regex=re.compile(r"""\A(\b\d{4},|\d{4}-\d{4},)*(\b\d{4}|\d{4}-\d{4})\Z""")
If this turns out ok, I do a find all with your expression, and then I get
the desired result.
