first type
I don't know if you remember, but I've written this before in my file handling program
Python file processing program
This program only requires the os, time library
import os,time
Then you can write the traversal code
for foldername,subfolders,filenames in (bianli_dir):
print('Current folder:'+foldername) #Output current folder π
for subfolder in subfolders: # Iterate through the subfolders in the current folder
print('In'+foldername+Subfolders in ':'+subfolder)
for filename in filenames:# Iterate over files in subfolders
print('In'+foldername+' in the file:'+filename)
The rest is a query, error reporting function, you can add to it according to their own preferences
Complete code (example)
print("Please answer the directory you want to traverse.")
bianli_dir=input(">>>")
try:
for foldername,subfolders,filenames in (bianli_dir):
print('Current folder:'+foldername) #Output current folder π
for subfolder in subfolders: # Iterate through the subfolders in the current folder
print('In'+foldername+Subfolders in ':'+subfolder)
for filename in filenames:# Iterate over files in subfolders
print('In'+foldername+' in the file:'+filename)
(1)
print(" ")
print("Traversal complete!")
except:
if FileNotFoundError:
print("There is no such catalog.")
else:
print("This folder cannot be traversed.")To test the program, I now have a folder called "111".
Run γγγγγγ
Success! Basic needs have been met
second type
This method is in the form of an interface to feedback the results, some people may say, the author, you use the messagebox module in tkinter not to be enough
That's true, but what if you want to traverse a particularly large folder?
Go bigger, the screen is full γγγγγ
At this point we have to think of a different way, and since we're talking about tkinter, let's use it!
briefcase
import os
import tkinter as tk
from import *
class Tree(object):
"""Traverse the catalog."""
def __init__(self,path):
=() #Creating windows
("Show Tree Catalog")
("400x400")
=Treeview()
("#0",text="file")
(width=400,height=400)
temppath=(path)# Extract the last filename in path
treeF=('',0,text=temppath)#1 level of catalog
(path,treeF)
()
def showtree(self,path,root):
filelist=(path) # Putting files from a folder into a list
for filename in filelist:
abspath=(path,filename)
# Add paths to the directory tree
treeFinside=(root,0,text=filename,values=(abspath))
if (abspath):
(abspath,treeFinside)Iteration code
lujing=input("Please enter a path to traverse.")
a=Tree(lujing)
Enter the path code

summarize
These are the two ways that python can traverse a directory, one that gives you the results as a printout, and another that gives you the results as a tkinter interface, the second of which is much more powerful and allows you to traverse any folder, no matter how big it is.
To this point this article on Python to achieve traversal of the directory of the two methods summarized in this article, more related Python traversal of the directory content, please search for my previous articles or continue to browse the following related articles I hope that you will support me more in the future!
