Here you're building credlist as a list of floats.

This is wasted effort

You've asked to loop through credlist, so each value of i is going to
be float. Maybe you should rename i to something that looks less like
an index and more like a credit.

Here, you're trying to indexa list with a float. No can do...

I think what you want is
for cr in credlist:
credits += cr
Which could also be implemented as
credits = reduce(lambda x,y: x+y, credlist)
Change is inevitable, progress is not.
