Summary of os file operation module methods in Python with mind map

The os module provides a very rich method for handling files and directories. This article will briefly introduce the commonly used methods, as shown in the following table:

The specific operations are as follows

import os

1. Switch working path

os.chdir("C:\软件")

2. Get the current working directory, that is, the directory path where the current Python script works:

os.getcwd()

'C:\\软件'

3. Return all file and directory names in the specified directory

os.listdir()

['basic-miktex-20.12-x64.exe',
 'EViews 10.0 64位.zip',
 'Navicat Keygen Patch v5.6.0 DFoX.exe',
 'navicat150_premium_cs_x64.exe',
 'nbpreview-master',
 'pandoc-2.0.1.1-windows.msi',
 'Snipaste-2.3.5-Beta-x64',
 'typora-setup-x64_0.9.78.exe']

4. Function to delete a file

os.remove("测试\测试.txt")

5. Delete multiple directories

os.removedirs("测试")

• Create a multi-level directory

os.makedirs("测试\测试")

6. Check if the given path is a file

os.path.isfile("EViews 10.0 64位.zip")

True

7. Check if the given path is a directory

os.path.isdir("EViews 10.0 64位.zip")

False

8. Determine whether it is an absolute path

os.path.isabs(r"C:\软件")

True

9. Check whether the given path actually exists

os.path.exists(r"C:\user")

False

10. Return the directory name and file name of a path

os.path.split('typora-setup-x64_0.9.78.exe')

('', 'typora-setup-x64_0.9.78.exe')

11. Separate extension

os.path.splitext('typora-setup-x64_0.9.78.exe')   

('typora-setup-x64_0.9.78', '.exe')

12. Run shell commands

os.system() 

0

13. Reorder

os.rename(old,new)

14. Get file size

os.path.getsize(filename)

0

15. Indicate which platform you are using

os.name

'nt'

For Windows, it is'nt', and for Linux/Unix users, it is'posix'
