You need to make changes to the python code, here is the changed one:

def something(tu):
   ch='a'
   for i in range(len(tu)):
      tu[i]=ch
      ch+='a'
l=[1,4,2,3,8]
something(l)
for i in l:
    print(i)
print("The end!")

The reason you may get error is, you have an 8 in your list. But the max length of the list is only 5. So change the i in that. Alternatively change the 8 to 0. It will work too. The index is out of bounds. I changed the indentation too.

  • You could highlight that `for i in tu` iterates over the elements themselves, while `for i in range(len(tu))` iterates over the *index*. Normally you would use `for index, element in tu` instead, since it is considered more pythonic. See [this answer](https://stackoverflow.com/a/522578/6725184) for more details. – Christian König Jun 14 '17 at 08:31
