如何遞歸地打印每個文件或文件夾的路徑名稱

Question

這裏是我的代碼和錯誤！請給我一個提示

import os 
def traverse(path, d): 
    for item in os.listdir(path): 
     item = os.path.join(path, d) 
     try: 
      traverse(path,d) 
     except: 
      print (path) 

我的錯誤：

traverse ("test",0) 
Traceback (most recent call last): 
    File "<pyshell#0>", line 1, in <module> 
    traverse ("test",0) 
    File "C:\Users\Phuchu\Desktop\Python\homework8.py", line 65, in traverse 
    for item in os.listdir(path): 
FileNotFoundError: [WinError 3] The system cannot find the path specified: 'test\\*.*' 

Answer 1

你可能更願意使用os.walk，這是更Python。它會將遞歸轉化爲一個簡單易懂的循環，並將管理遍歷到您的目錄中。

Answer 2

使用os.walk

import os 

def traverse(current_dir): 
    for root, dirs, files in os.walk(current_dir): 
     #print all files recursively 
     for file in files: 
      print os.path.join(root,file) 
     #print all folders recursively 
     for dir in dirs: 
      print os.path.join(root,dir)
