I don't know how to do this question

it says

Bummer! Be sure to use integers for indexes. int() or // will be needed!

sillycase.py
def sillycase(st):
    x=list(st)
    y=x/2
    return str[ :y].lower() + str[y:].upper()

While adding the second division slash is important, there are a few more errors

  • in calculating y, you need to use the len(x) instead of x
  • in the return statement, the built-in function str should be the parameter st instead

Post back if you need more help. Good luck!!!

Division generates floats by default, but the "//" operator is the special "integer division" operator:

    y=x//2

And as the challenge hinted, you could also pass the entire expression as the argument to "int()".

I have put two divide symbols in, and it still says the same thing
