34,222 PointsUnderstanding Double Unders __main__
Can someone with experience give me a hint on this? I just want to know whether or not it is considered good practice or standard to add a main() function and dunder check to your source code files when designing a python package (multiple files that work together):
Edit: And what is the standard code order here?
- import statements
- class and function definitions
- main function
- dunder check
def some_module_function():
pass
def main():
# main code goes here
some_module_function()
if __name__== "__main__":
main()
Or can I just have my 'main code' bare in the file?

and calling it from the if __name__ == '__main__'
bit. Some people have other preferences. It isn't 100% standardized, but most people prefer having a main
function.
And yes, usually the structure of a program goes as follows:
- Imports
- Classes
- Functions
- Main function
if __name__ == '__main__'
