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

Use os.path.abspath():

os.chdir(os.path.dirname(os.path.abspath(sys.argv[0])))

sys.argv[0] in your case is just a script name, no directory, so os.path.dirname() returns an empty string.

os.path.abspath() turns that into a proper absolute path with directory name.
