Here's a few hints:

  • you won't know how long the string will be, so you can't used fixed values in the slice
  • the names of the functions for changing case are ".lower()" and ".upper()"
  • you'll need to combine the two new parts together
  • you'll need to "return" the combined result
  • you only need to define the function, you don't need to call it yourself

You can perform string concatenation with the "+" operator.

Emilio! In your code you set the string halves with a slice, You have assumed the length of that string. You might not have the strings length right if you guessed. Better to get the length with len() as len(your_string) then cut it in half as len(your_string)/2...this integer will help you indexing the halves of your_string.

another problem is the way you're trying to change cases? the method is lower() or upper() as in half_a_string.lower()

i hope this helps you. If you're struggling with a method like .lower(), upper() or len() go to the python docs they're helpful once you get onto them. Good luck.
