GitHub - pavelbraginskiy/startpoint: A saner replacement for `if __name__ == “__main__”`

startpoint

pip install startpoint

A simple python module providing a sane alternative to if __name__ == "__main__"

To use, simply declare an entry point like so:

from startpoint import entrypoint

@entrypoint(__name__)
def main():
    print("Hello, World!")

In this example, main will be called only if the file is executed directly, not if imported. You can also specify a behaviour that will happen when the module is imported:

@entrypoint(__name__, alt=lambda:print("I'm not a library!"))
def main():

You can also declare an entry point that take an argument, in which case sys.argv will be passed in:

@entrypoint(__name__)
def main(args):
