you can make the file usable as a script as well as an importable module, because the code that parses the command line only runs if the module is executed as the “main” file: 你不但可以把它当脚本使用,还可以称为可导入的模块,因为分析命令行的代码仅仅当模块的文件名为main.py时才会被执行。
pathCurrent = os.path.dirname(os.path.dirname(__file__)) path.append(pathCurrent) import AAA.test01 ===输出结果=== 我是一条可执行语句 4、_name_的用法 作用:“Make a script both importable and executable” 如果我们是直接执行某个.py文件的时候,该文件中: ”_name== '_main_'“ 是True ...
1 import importable1,importable2,... 2 import importable as preferred_name #将导入的模块自定义名称。如果模块是一个包或包中的一个模块,则需将每一部分用"."进行分隔。 3 from importable import * #将包内的所有内容都导入 4 from importable import object1,object2,... 5 from importable import ob...

有句话经典的概括了这段代码的意义:“Make a script both importable and executable”意思就是说 可执行 函数定义 不执行 原创 sb14188 2022-07-25 16:41:32 108阅读 python内置属性__name__ 在Python中,内置属性 `__name__` 是一个非常重要的概念。它用于表示模块的名称,在判断模块是否为主模块时非常有...
“Make a .py both importable and executable” 如果我们是直接执行某个.py文件的时候,该文件中那么"__name__ == '__main__' "是True,但是我们如果从另外一个.py文件通过import导入该文件的时候,这时__name__的值就是我们这个py文件的名字而不是__main__. ...
所以代码if __name__ == '__main__':实现的功能就是Make a script both importable and executable,也就是说可以让模块既可以导入到别的模块中用,另外该模块自己也可执行。 安装第三方模块 在Python中,安装第三方模块,是通过包管理工具pip完成的。
