no additional indentation with if __name__ == "__main__":
idioms, program-entry-point, python
Solution
Nope, not possible, really.
When `__name__` is not `'__main__'` your module was imported by another piece of code, as a regular module. You cannot bail out early in that case.
And what's wrong with a one time extra indentation level? Just hit tab in the editor, and be done with it? Personally, I find that using a `main()` function documents the intent much better than leaving the code unindented.
Problem
i know that it is good style to define a main() method for "script-style" python programs so it can optionally be included as a module later on. so let's assume this code (random snippet): ``` a = 5 if a > 0: print a ``` becomes ``` def main(): a = 5 if a > 0: print a if __name__ == "__main__": main() ``` causing all my code to be indented one more level. i try to avoid unnecessary indentation/nesting in my code for maximum clarity, and thus i am wondering if something can be done here, like e.g. ``` if __name__ != "__main__": return # just leave this file a = 5 if a > 0: print a ``` but (of course) this triggers: ``` SyntaxError: 'return' outside function ``` is something like this possible? advisable? idiomatic?
