Python: OSError: [Errno 2] No such file or directory: ''

Question

I have a 100 lines, 3 years old python scraper that now bug. Starting lines are:

import urllib, re, os, sys, time    # line 1: import modules
os.chdir(os.pat         


        

Answer 1

I had this error because I was providing a string of arguments to subprocess.call instead of an array of arguments. To prevent this, use shlex.split:

import shlex, subprocess
command_line = "ls -a"
args = shlex.split(command_line)
p = subprocess.Popen(args)
