在上述代码中,我们首先使用import语句引入了math_functions模块(即math_functions.py文件)。然后,我们可以直接使用math_functions模块中的函数,如math_functions.square和math_functions.cube。 最后,我们通过调用这些函数并打印结果,验证了在main.py中成功调用了math_functions.py中的函数。 在实际应用中,我们可以根据需要...

Or perhaps you don't actually want to run moduleX, you just want to run some other script, say myfile.py, that uses functions inside moduleX. If that is the case, put myfile.py somewhere else – not inside the package directory – and run it. If inside myfile.py you do things ...
在命令行窗口执行python script-file.py,以执行 Python 脚本文件。 指定解释器 如果在 Python 脚本文件首行输入#!/usr/bin/env python,那么可以在命令行窗口中执行/path/to/script-file.py以执行该脚本文件。 注:该方法不支持 Windows 环境。 编码 默认情况下,3.x 源码文件都是 UTF-8 编码,字符串都是 Unicode...
