mod_python not detecting files when using open()

Question

I am trying to open a file I have in my /var/www/ directory named cardlist.xml. this is the code I am using.

import cgi
import os
open("./cardlist.xml", "r")
def crawlXml():
    return 0

My error is

This is the result of ls -la in the

Does anyone know what is going wrong?

Answer 1

The working directory might not be the directory of the file. Try using an absolute path, or an explicitly relative path:

import os.path
open(os.path.join(os.path.dirname(os.path.abspath(__file__)), 'cardlist.xml'))
