Python scripts execute top-to-bottom upon invocation, unlike compiled languages that mandate a specific entry function like main(). This dynamic execution model creates a conflict when a source file serves dual purposes: acting as an executable script and functioning as an importable library. The conditional block if __name__ == "__main__& ...
