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)
