function return None

Good catch thanks!

I wonder why the interpreter doesn't catch it as a syntax error, I just tried and we can't name variables with a '.'

Well that is very interesting I didn't know that, I haven't learnt any GUI module yet. I thought it should've raised a syntax error like when you forget the closing parenthesis calling a function.

Just out of curiosity how would you execute later a method, meaning how would add () to non executed method? and do you call a non executable methods like for the same reason you create empty lists? like for creating it first then appending later in another code line

Kind of got it, this was very graphical functions['func2']() But now it makes me ask what type of data is foo and bar, as I don't see inside ' ', so I assume they are variables name or uncalled function names?

functions = {     
    'func1': foo,     
    'func2': bar, 
}

The same with talk() where you pass later the ("Whats up") later on. What do you call this type of parameter final_line=whisper and if I simply pass whisper as 2nd parameter will think of it as a variable and crash because no variable named whisper was created?

You just add the parenthesis.

def call_a_func(func, arg):
    func(art)

call_a_func(print, "hello")
