Nigel Belderbos ,
line 2:
number=input("")

This takes input from user and assigns it to `number` variable.
But the input is of type str (String) and not integer

line 5:

Here you compare str object `number` with integer 5 .

Comparison between string and integer is not valid. So when you take input you need to convert input string to integer ,like this :

number=int(input())
