Python's syntax allows for code to be significantly shortened by using something calledmodules.Similar to header files in C++, modules are a storage place for the definitions of functions. They are separated into common uses, such as the time module, which provides functions for time related use...

相比绝对导入,相对导入不受到sys.path的限制,它的限制在于不能import入口点平级或以上的数据包,更不能把带有相对导入的python文件当入口点。如果你明白了入口点是什么,结合上述例子,相关报错应该很容易排查。 老实说,相对导入并不是一种解决import报错的方案,而是一种简化代码的方案。 它解决的其实是之前的例子里mod...
Python中的模块是一种包含Python代码的文件，用于封装功能、代码逻辑和类，实现代码的结构化与模块化。引入模块主要有以下几种方式：使用import语句引入模块：例如，import os，引入后可以直接调用os模块内的函数或方法。这种方式避免了命名冲突，使代码更加清晰。使用import语句结合as关键字为模块命名别名：例如...
