ZeroDivisionError: float division (baby steps)

[Diez B. Roggisch]

I reduced the code to the lines that actually do something with count:

> count= 0
> count= count + 1
> count= count -1

This yields count beeing 0 - thus you get a ZeroDivisionError, as one has to
expect for division by zero....

I'm not totally sure what you actually want, but it seems to me that you
should indent the lines

count= count + 1
sum= sum + number

to the same level as the loop - that will make them part of the loop, so you
actually get some numbers accumulated.
