Python implements tree printing directory structure_python
This article mainly introduces the relevant code of python tree printing directory structure in detail. It has certain reference value. Interested friends can refer to it.
The example of this article shares python with everyone. The specific code for tree printing directory structure is for your reference. The specific content is as follows
Preface
When I was sorting out the data files in the past two days, I found that there were many clicks one after another. Folder viewing is very tedious, so I wanted to write a tool to recursively print out the tree structure of the file directory. I found some information on the Internet and almost all used os.walk, and debugged it. Later, I found that what was returned seemed to be a "generator", which only required a for loop. However, the structure obtained in this way seemed to be the BFS structure, not the tree structure I wanted. Finally, I finally found out os.listdirThis function, but use it to write a depth-first search, as long as the recursive call can solve my problem.
Code
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
#a test for traverse directory
__author__ = 'AlbertS'
import os
import os.path
def dfs_showdir(path, depth):
if depth == 0:
print("root:[" + path + "]")
for item in os.listdir(path):
if '.git' not in item:
print("| " * depth + "+--" + item)
newitem = path +'/'+ item
if os.path.isdir(newitem):
dfs_showdir(newitem, depth +1)
if __name__ == '__main__':
dfs_showdir('.', 0)Running effect

Summary
When I first wrote it, I found that I could only recurse one level of folders. Later I found that the problem occurred in the os.path.isdir function.
The parameter passed to the os.path.isdir function can only be an absolute path, or a relative path relative to the working directory.
With the problems discovered above, the process of splicing newitem variables was born.

Can vs code run in Windows 8
Apr 15, 2025 pm 07:24 PM
VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.
