*Never* ever use a bare except clause. *Always* specify wich exceptions
you are expecting. (NB : here, TypeError and ValueError).

(NB :  of course, like for all and any do's-and-don't rules, there are
actually a very few cases where using a bare except may be ok.)

Nope. At this stage, 'something' is *not* an int - it's a string that
can be turned into an int.

You don't need the "type('')" stuff - use isinstance(something,
basestring) instead.
