We often deal with files and directories. For these operations, python provides an OS module that contains a lot of functions for operating files and directories. All functions can be viewed using help (OS) or dir (OS. Common functions are as follows: 1. rename: OS. rename (old, new) 2. delete:

The OS. path module mainly integrates the path folder operation function. here we will take a look at the operation method summary in the OS. path module in Python. For more information, see Resolution pathPath parsing dependency and some variables defined in OS: OS. sep-delimiter between all parts of the path.

The OS module provides a number of features that allow your program to interact directly with the operating systemGets the current working directory, which is the directory path of the current Python interpreter work: OS. getcwd() returns all file and directory names under the specified directory: OS. listdir() function to delete a file:
