问题描述

认为标题总结了问题:-)

Think the title summarizes the question :-)

推荐答案

脚本通常是一段可直接执行的代码，由其自身运行.模块通常是一个库，由其他代码段导入.

A script is generally a directly executable piece of code, run by itself. A module is generally a library, imported by other pieces of code.

请注意，没有内部区别 -- 两者都是可执行的和可导入的，尽管库代码在直接执行并导入旨在用于成为脚本将导致它执行，因此常见的 if __name__ == "__main__" 测试.

Note that there's no internal distinction -- both are executable and importable, although library code often won't do anything (or will just run its unit tests) when executed directly and importing code designed to be a script will cause it to execute, hence the common if __name__ == "__main__" test.
