使用os.walk()在Python中递归遍历目录

我想从根目录导航到所有其他目录，并打印相同的内容。

这是我的代码:

#!/usr/bin/python

import os
import fnmatch

for root, dir, files in os.walk("."):
        print root
        print ""
        for items in fnmatch.filter(files, "*"):
                print "..." + items
        print ""

这是我的O/P:

.

...Python_Notes
...pypy.py
...pypy.py.save
...classdemo.py
....goutputstream-J9ZUXW
...latest.py
...pack.py
...classdemo.pyc
...Python_Notes~
...module-demo.py
...filetype.py

./packagedemo

...classdemo.py
...__init__.pyc
...__init__.py
...classdemo.pyc

以上,。和。/packagedemo是目录。

不过，我需要以下列方式列印订单:

A
---a.txt
---b.txt
---B
------c.out

上面，A和B是目录，其余是文件。

试试这个吧;简单的

 #!/usr/bin/python
 import os
 # Creating an empty list that will contain the already traversed paths
 donePaths = []
 def direct(path):
       for paths,dirs,files in os.walk(path):
             if paths not in donePaths:
                    count = paths.count('/')
                    if files:
                          for ele1 in files:
                                print '---------' * (count), ele1
                    if dirs:
                          for ele2 in dirs:
                                print '---------' * (count), ele2
                                absPath = os.path.join(paths,ele2)
              # recursively calling the direct function on each directory
                                direct(absPath)
                   # adding the paths to the list that got traversed 
                                donePaths.append(absPath)

 path = raw_input("Enter any path to get the following Dir Tree ...\n")
 direct(path)

输出= = = = = = = = = = = = = = = =

 /home/test
 ------------------ b.txt
 ------------------ a.txt
 ------------------ a
 --------------------------- a1.txt
 ------------------ b
 --------------------------- b1.txt
 --------------------------- b2.txt
 --------------------------- cde
 ------------------------------------ cde.txt
 ------------------------------------ cdeDir
 --------------------------------------------- cdeDir.txt
 ------------------ c
 --------------------------- c.txt
 --------------------------- c1
 ------------------------------------ c1.txt
 ------------------------------------ c2.txt

你也可以使用pathlib.Path()递归地遍历一个文件夹并列出它的所有内容

from pathlib import Path


def check_out_path(target_path, level=0):
    """"
    This function recursively prints all contents of a pathlib.Path object
    """
    def print_indented(folder, level):
        print('\t' * level + folder)

    print_indented(target_path.name, level)
    for file in target_path.iterdir():
        if file.is_dir():
            check_out_path(file, level+1)
        else:
            print_indented(file.name, level+1)


my_path = Path(r'C:\example folder')
check_out_path(my_path)

输出:

example folder
    folder
        textfile3.txt
    textfile1.txt
    textfile2.txt

这是对文件夹名称的处理:

def printFolderName(init_indent, rootFolder):
    fname = rootFolder.split(os.sep)[-1]
    root_levels = rootFolder.count(os.sep)
    # os.walk treats dirs breadth-first, but files depth-first (go figure)
    for root, dirs, files in os.walk(rootFolder):
        # print the directories below the root
        levels = root.count(os.sep) - root_levels
        indent = ' '*(levels*2)
        print init_indent + indent + root.split(os.sep)[-1]

这是最好的办法吗

import os

def traverse_dir_recur(directory):
    l = os.listdir(directory)
    for d in l:
        if os.path.isdir(directory + d):
            traverse_dir_recur(directory +  d +"/")
        else:
            print(directory + d)

给定一个文件夹名称，递归遍历其整个层次结构。

#! /usr/local/bin/python3
# findLargeFiles.py - given a folder name, walk through its entire hierarchy
#                   - print folders and files within each folder

import os

def recursive_walk(folder):
    for folderName, subfolders, filenames in os.walk(folder):
        if subfolders:
            for subfolder in subfolders:
                recursive_walk(subfolder)
        print('\nFolder: ' + folderName + '\n')
        for filename in filenames:
            print(filename + '\n')

recursive_walk('/name/of/folder')

这会给你想要的结果

#!/usr/bin/python

import os

# traverse root directory, and list directories as dirs and files as files
for root, dirs, files in os.walk("."):
    path = root.split(os.sep)
    print((len(path) - 1) * '---', os.path.basename(root))
    for file in files:
        print(len(path) * '---', file)
