Those are two patterns.

I think that anything matched by \d will also be accepted by int().

The reason I did not use \d\d* or \d+ or ^\d+$ or any number of
more-correct things was because the OP was new to regexps.

Yes, good catch! I had failed to reduce your original
pattern down to it's most fundamental aspe

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 leadin

Well of course it matched, because your pattern defines "one
or more consecutive digits". So it will match the "1" of
"1a" and the "11" of "11a" likewise.

In related news, the regexp I gave for numbers will match "1a".
