trouble with fizzbuzz challenge

All input from the user is received as a string. So "15" will need to be converted using int() first.

>>> number = "15"
>>> is_fizz = number % 3 == 0
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: not all arguments converted during string formatting
>>> 
>>> is_fizz = int(number) % 3 == 0
>>> is_fizz
True

Some coders choose to place the input() within an int() to covert the user input immediately into an integer. This could raise a warning if the user enters something that can't be converted into an integer.

You may be asking how this happens. When the operator % has a left-side argument that is a number, the operator is interpreted as the arithmetic modulo.

In addition to performing the modulo operation on numbers, the % operator is also overloaded by string objects to perform old-style string formatting (also known as interpolation). The syntax for string formatting is described in the Python Library Reference, section printf-style String Formatting.

Post back if you need more help. Good Luck!!
