Your variable names need a bit more thought

What is a "bin"? Maybe you shoulc have called this a "lst" eh?

Why would you call a list of numbers (that's plural BTW) the singular
name "num"? Not to mention that even "numbers" is the wrong
identifier. Use "averages" instead. Heck, even "buffer" would have
been a better choice that "num".

Not every "item" in the lst is a number so we should use the generic
"item" identifier here.

What the hell is a loop doing here???

This block of logic is ugly. Try this instead...

>             if number == 'end':
>                 break
>             number=float(number)
>             total += float(number)
>             count+=1
>             avg = total/count

...but that whole loop thing is nonsense anyway. I would reconsider
this code completely. Here is an outline:

for item in lst
    if item equals "end":
        compute the current average from buffers
        increment the running total
        increment the count.
