Now here is the crucial thing for your error message: if a module's name has no dots, it is not considered to be part of a package. It doesn't matter where the file actually is on disk. All that matters is what its name is, and its name depends on how you loaded it....

模块(Module)是一个以.py结尾的python文件,在文件中我们定义了函数、类,准备以后重用这些代码块。Python中模块的名字,就是以.py为后缀的文件的文件名,例如fibo.py,那么模块名就是fibo。__name__变量保存了引用的模块的名字,当模块被当做主模块执行时,则__name__等于__main__。
python doc:__file__is the pathname of the file from which the module was loaded, if it was loaded from a file. 如果一个模块是从文件加载的,__file__就是该模块的路径名。 顾名思义,当模块以文件的形式出现__file__指的是模块文件的路径名,以相对路径执行__file__是相对路径,以绝对路径执行_...
Python's pathlib module enables you to handle file and folder paths in a modern way. This built-in module provides intuitive semantics that work the same way on different operating systems. In this tutorial, you'll get to know pathlib and explore common
