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。

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')

其他回答

/home/parent_dir
├── 0_N
├── 1_M
├── 2_P
├── 3_R
└── 4_T

下面是你可以估计每个子目录中#文件相对于父目录中#文件总数的大致百分比:

from os import listdir as osl
from os import walk as osw
from os.path import join as osj

def subdir_summary(parent_dir):
    parent_dir_len = sum([len(files) for _, _, files in osw(parent_dir)])
    print(f"Total files in parent: {parent_dir_len}")
    for subdir in sorted(osl(parent_dir)):
        subdir_files_len = len(osl(osj(parent_dir, subdir)))
        print(subdir, subdir_files_len, f"{int(100*(subdir_files_len / parent_dir_len))}%")

subdir_summary("/home/parent_dir")

它将在终端中打印如下:

Total files in parent: 5876
0_N 3254 55%
1_M 509 8%
2_P 1187 20%
3_R 594 10%
4_T 332 5%

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)

在os包中有更适合的函数。但是如果你必须使用操作系统。走吧，这是我想到的

def walkdir(dirname):
    for cur, _dirs, files in os.walk(dirname):
        pref = ''
        head, tail = os.path.split(cur)
        while head:
            pref += '---'
            head, _tail = os.path.split(head)
        print(pref+tail)
        for f in files:
            print(pref+'---'+f)

输出:

>>> walkdir('.')
.
---file3
---file2
---my.py
---file1
---A
------file2
------file1
---B
------file3
------file2
------file4
------file1
---__pycache__
------my.cpython-33.pyc

#!/usr/bin/python

import os 

def tracing(a):
    global i>
    for item in os.listdir(a):
        if os.path.isfile(item):
            print i + item 
        else:
            print i + item 
            i+=i
            tracing(item)

i = "---"
tracing(".")
