If you remove the "__main__" name, then you will still need to have some attribute for python to determine the same thing.
Why? There is nothing saying we can't follow most other languages and just have a reserved function name that gets executed if the module is executed.
Yes, but this is where python is different from other languages. In a way, python's main *is* the whole module from the top to bottom. And so the '__main__' name is referring to the whole module and not just a function in it.
A more specific function would be needed to get the context right. Maybe __script__(), or __run__().
Or if you want to be consistent with class's, how about adding __call__() to modules? Then the main body of the module effectively works the same way as it does in a class. =)
Hey, I think that has some cool possibilities, it makes modules callable in general. So if I want to run a module's __call__(), AKA main() as you call it, after importing I would just do...
import module module()
And it would just work. ;-)
I like this idea. Makes it very obvious. You just say "when a specific module is specified at the command line it is called. Could even have it take possibly sys.argv[1:] (which I think was supposed to turn into sys.args or sys.arg or something at some point).
What do other people think?
