os.mkdir() “mkdir”,即“make directory”,用处是“新建一个路径”。需要传入一个类路径参数用以指定新建路径的位置和名称,如果指定路径已存在,则会抛出FileExistsError异常。 该函数只能在已有的路径下新建一级路径,否则(即新建多级路径)会抛出FileNotFoundError异常。

Python os 模块详解 1. 简介 os 就是“operating system”的缩写,顾名思义, os 模块提供的就是各种 Python 程序与操作系统进行交互的接口。通过使用 os 模块,一方面可以方便地与操作系统进行交互,另一方面页可以极大增强代码的可移植性。如果该模块中相关功能出错,会抛出 ...
A good make-directory function should, first of all, make the necessary parent directories, which os.makedirs does quite nicely. We also want our function to complete silently if the directory already exists but to fail if the needed directory exists as a plain file. To get that behavior, ...
