python keeps opening script directory

[Tyrel]

Could someone please help,

openwebsites.py:

import webbrowser
import os


def websites():
    websitelist = "Setup1\\web_value.txt"
    websites = []
    browser = webbrowser.get("windows-default")
    for line in open(websitelist, "r").readlines():
        websites.append(line.strip())
    for website in websites:
        browser.open(website)
websites()

This script opens a list of websites from a file that holds the urls. it works perfectly but it keeps opening the directory of openwebsites.py. What am I doing wrong?
