That won't help, type(start) is a type object, not a string.

It's also possible that Ian is entering an integer, he didn't show the
input value:
In [1]: print type(input('Enter a number: '))
Enter a number: 123
<type 'int'>

Alan G's solution - explicit conversion using float() with an
exception handler - is the best way to do this.
