Re: Modulo of 4 not working right

I'm not sure how to put the "better fix", would it be in the while statement? should it be child of the statement?

I tried the "simple fix" and it isn't working either. It returned a list of 33 items in one of the sections, that would work out to 8.25. Obviously it is divisible, but i dont want it to be a float for obvious reasons, can you clarify for me?

The 'simple fix', to remove 'not' from the statement works because of how modulo works, which works like this:

   >>> 10 % 4
   2

The modulo returns the /remainder/. It will not be a float.

Let's see how this evaluates::

   >>> if 10 % 4:
   ...    print "true"
   ...
   true







Hopefully that helps!

If the modulo returns anything other than 0, it will evaluate to True. In python any integer other than 0 evaluates to True. You are treating modulo like it is an operation to find out if the second number goes into the first number an even amount of times. That's why removing the 'not' is the 'simple fix'. So if there isn't enough fields for 4 columns, say 11, 11 % 4 will evaluate to true. Add one more, and 12 % 4 will evaluate to false. The 'good fix' is set up to do the logic all at once. Because modulo returns an integer, you can just set the number of blank fields to the number that modulo returns.
