[CONTINUED FROM LAST REPLY...] Likewise if your intent is to filter out any match strings which contain non-digits, then define the start and stop points of the pattern:
# Match only if all are digits >>> re.match(r'\d\d*$', '111aaa222') # fails # Match only if all are digits and, # allow leading white-space >>> re.match(r'\s*\d\d*$', ' 111') <_sre.SRE_Match object at 0x026D8410> # But not trailing space! >>> re.match(r'\s*\d\d*$', ' 111 ') # fails -- https://mail.python.org/mailman/listinfo/python-list
