module detecting if imported vs not

[Skaperen]

how can a module detect if it is being imported, possibly by a command script, as opposed to being run directly?

[Yoriz]

a module can discover whether or not it is running in the top-level environment by checking its own __name__, which allows a common idiom for conditionally executing code when the module is not initialized from an import statement:

if __name__ == '__main__':
    # Execute when the module is not initialized from an import statement.
    ...
