Maybe you can use the "in" instead of "==", meaning that a certain
string conforms to a certain pattern, that defines an implicit class
of possibilities, so with the "in" you look if the string is present
in that class of acceptable patterns, instead of being equal to that
class.

integers = Word(nums)
if "123" in integers:
    # do something

print [x for x in "123 234 asld".split() if x in integers]
# prints ['123', '234']
