If you want to see the difference between the number and string 
representation thereof, use repr(x).

 >>> print(repr(3), repr('3'), [3, '3'])
3 '3' [3, '3']

Note that printing a collection prints the repr() of each item precisely 
so one can tell the difference between the item being a number or a string.
