Why is this function printing the number of keys in a dictionary?

[woooee]

1 def dictKeysOnly (dictionary):
----> 2 lst = [{dictionary}]
3 lst = sorted(lst)
4 return (lst)
5 print("List in ascending order: ",sorted(dictionary))

This is different from the first code you posted, and as such shows a different error message. Note that the print statement will never be reached if is is indeed under the def.

What do you mean by it's not defined outside the function

The original message "NameError: name 'dictionary' is not defined" which was likely caused by the print statement not being indented under the function def.
