I will give you a hint here, though. You should definitely test this in a workspace. I can promise you that the only thing you will get back is a lower case string and this is because a function ceases execution when a return statement is hit :sparkles:

Hi there, Ashmit! I will try again with some addition tips:

  • This challenge can be completed in two lines of code.
  • The function is not taking multiple strings. It is only taking one string. A loop is unnecessary.
  • The uppercase version of that string, the lowercase version, the title case version and the reverse version should all be returned together on the same line
  • You should return a list with the different versions inside and separated by commas
  • Your code is currently missing the title case
  • If I sent in "Hello", I would expect to get back a tuple containing "hello", "HELLO", "Hello", "olleH"

Give it another go and test it in the workspace! :sparkles:

The flow of your code needs work. In the first for loop, the return will stop the function execution in the first iteration.

Sometimes it helps to understand the challenge by making sure you are fully reading all the text.

The challenge asks you to create a function that "takes a single string" and returns "a tuple of different string formats".

Using a for loop on a string will iterate over ever individual letter.

Instead, capture each version of the modified string in a different variable, then return a tuple containing these variables. The solution can be more compact than this but it's helpful to understand how to do each step explicitly before jumping to shortcut notation.

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