def show_help(): print("Type 'HELP' if help is needed \n Type 'DONE' when you're done") show_help()
while True: name = input("Hello input please......... ") if name == "DONE": break elif name == "HELP": show_help() continue
A quick one, when I switch: show_help() continue to: continue show_help()
It doesn't work. Can I know why. cheers

You are asking whether or not you can safely switch the order of the show_help()
and continue
statements in your program, correct? If so, let us look at what happens logically when you try to do so. When you switch the order of show_help()
and continue
like you just described, it causes your program to behave in a way that is not quite right. Do you see what it is? Remember, the continue
statement causes the program to return to the beginning of the while
loop as soon as the program encounters it. Therefore, if you place continue
above your call to show_help()
, then show_help()
will never run because your program will return to the beginning of the loop before show_help()
has a chance to execute. Does this help?

Please ensure that you always properly format your code, following the guidance in the Markdown Cheatsheet (linked below the answer entry box).
This is always important for code readability but absolutely critical when dealing with Python where whitespace is significant.
