Python file-io代码列出了当前文件夹路径而不是指定的路径

Question

I have the code:

import os
import sys

fileList = os.listdir(sys.argv[1])
for file in fileList:
    if os.path.isfile(file):
        print "File >> " + os.path.abspath(file)
    else:
        print "Dir >> " + os.path.abspath(file)

Located in my music folder ("/home/tom/Music")

When I call it with:

python test.py "/tmp"

I expected it to list my "/tmp" files and folders with the full path. But it printed lines like:

Dir >> /home/tom/Music/seahorse-gw2jNn
Dir >> /home/tom/Music/FlashXX9kV847
Dir >> /home/tom/Music/pulse-DcIEoxW5h2gz

This is, the correct file names, but the wrong path (and this files are not either in my Music folder).. What's wrong with this code?

Answer 1

You need to include the full path to the file when you check for existence and print the path:

dir = sys.argv[1]

fileList = os.listdir(dir)
for file in fileList:
    file = os.path.join(dir, file)  # Get the full path to the file.
    # etc...
