It is 2 lines of code that a beginner does not need to write at all.
I see a lot of short scripts that do not bother with the main function at all,
they just put all the code at module level. And why not?
Indeed I do not bother for short scripts either.
Once someone is doing more complex scripting then the benifits of the
2 lines and main function become something worth understanding and using.
Namely it allows importing the code and testing it.
