Hi! I'm looking for a trick or hidden feature to make Python 3 automatically call a "main" function but without programmers writing `if __name__ == "__main__": ...`
I found rejected PEP 299, but i thought that maybe there's something new already. Here's why I want such a thing: I'm teaching introductory programming course with Python. I've seen that global variables attract beginners like honey attracts bees and this makes teaching function parameters harder. When students learn functions, they usually write their function definitions and function applications in the same scope -- in top-level of the module (don't know the correct term for it). This has the downside, that any variable introduced in top-level is automatically visible in function definitions and I have hard time convincing students not to use those variables in functions directly. I've been thinking that it might be better for teaching if all program code would be in functions. This would make "Hello World" a bit more difficult, but would help teaching the "real thing" ie. functions. best regards, Aivar
