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。

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

import os

os.chdir('/your/working/path/')
dir = os.getcwd()
list = sorted(os.listdir(dir))
marks = ""

for s_list in list:
    print marks + s_list
    marks += "---"
    tree_list = sorted(os.listdir(dir + "/" + s_list))
    for i in tree_list:
        print marks + i

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]

#!/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(".")

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')

        for f in files:
            print(pref+'---'+f)

输出:

---file1

------file2
------file1
---B
------file3
------file2
------file4
------file1
---__pycache__
------my.cpython-33.pyc
