Hi Trying to clarify why ints and strings arent treated the same.
You can get a valuerror from trying to cast a non-int to an int as in int(3.0) however you cannot do a non string with str(a). Which means that you likely should use try and except to test if a user enters a non-int with valuerror. However as you can't str () and get a valuerror you use conditional logic with strings. Therefore to try and keep with pythons only one obvious way of doing things should i prefer conditional logic for all using isinstance? That way regardless of input type my code flows the same and more explicitly states the intended type. Sayth -- https://mail.python.org/mailman/listinfo/python-list
