Python's if __name__ == "__main__" Explained
Ever wonder what Python's "if name == main" construct does?
This Python tutorial will quickly explain what the if name == main condition does when added to your code.
The quick explanation?
Any time you want a single-point of entry for your Python apps, just put the code that kicks off your app in this block:
if _name_ == '__main__':
Then, when you run your Python app as a standalone application, the code in the if __name__=="__main__" block runs.
This is a smart approach if you want either run or import Python code as a library or a component.
It's similar to the void main() syntax of Java. C and C++ has similar constructs.
So there you go, that's the answer to the age old question of what does Python's if __name__=="__main__": do.
