I have this python code- i have two lists with two different values - some of the values are found in both lists. i want to check if the values in list 1 is also in list 2. if true append them to a third list. if not append all the values of list 1 to a separate list -

current code-

from bs4 import BeautifulSoup

import requests

import sys

def courses_from_catalog(filename):

courses_from_file = courses_and_sections(filename)

courses_on_the_site_and_file = []

school_course_catalog = []

school_course_catalog_only = []

URL = ['https://catalog.endicott.edu/content.php?catoid=38&navoid=1461', 'https://catalog.endicott.edu/content.php?catoid=42&navoid=1765', 'https://catalog.endicott.edu/content.php?catoid=44&navoid=2164']

for url in URL:

response = requests.get(url , timeout = 2)

content = response.text

soup = BeautifulSoup(content , "html.parser")

courses = soup.find_all('ul' , class_="program-list")

for course in courses:

for i in course.find_all('a'):

course_text = i.text.strip()

school_course_catalog.append(course_text[:7])
