函数func_out()里的变量 str1 = str1 + " World" func_inner() return str1 if __name__ == "__main__": print(func_out()) 结果： Hello World ★第6章、python3内置函数 内置函数是指不用import导入任何模块就能直接使用的函数 包名x 下的__init__.py里的 __all__=[这里列出的函 数及变量] 一个模块被另一程序第一次导入时，其主程序将运行，若不想让它运 行，可做个判断： if __name__=="__main__": #被导入模块的主程序写这里，只有它自己执行时才运行这里的代码 else: #来自另一程序的调用 import sys as xx #将导入的模块名 tar.gz模块安装包一样打包我们的源代码并执行setup.py去安装我们 的代码模块，可以使用distu�ls模块里的setup函数去打包 例如，我们写的代码有cof.py及lee.py两个模块，main.py只是用于测试 的主函数 现在需要把cof.py及lee.py打包成一个安装包 在我们的源程序目录下再创建一个setup.py文件，内容如下： from distutils.core import

Some features are missing on Windows (including multi-process mode) and scalability is limited (Even though Tornado is built on asyncio, which supports Windows
