Issues Scraping Facebook using facebook_scraper

[DustinKlent]

I'm scraping facebook groups using Facebook_Scraper but I am experiencing issues with it.

Here's the code I have:

import operator
from facebook_scraper import get_posts
from wordlist import words


title_list = []

for submission in get_posts(group = "nintendo", pages=1):
	titles = str(submission['text'][:10])
	titles = titles.replace("\n", " ")
	title_list.append(titles)
	word_list = [word for line in title_list for word in line.split()]

filtered_words1 = [word for word in word_list if word in words]

print(filtered_words1)

The file wordlist.py contains only the following:

words = ["Python"]

Here's the following error I receive:

Error:
Traceback (most recent call last):
  File "main.py", line 15, in <module>
    filtered_words1 = [word for word in word_list if word in words]
NameError: name 'word_list' is not defined

I'm not sure why it's throwing the error. word_list is defined clearly enough.

word_list is only defined within the for loop. If get_posts is empty, the loop is not run.

If there were posts, the filtered_words1 assignment would only be using the word_list that was set on the last iteration of the loop. The earlier posts wouldn't contribute. That seems incorrect to me.

As the word_list construction relies only on title_list, I think it needs to be moved outside the loop.

How would you adjust it? I'm not 100% sure I understand what you mean.

Line 12 is inside the loop. Get rid of the indent so that it runs after the loop is complete.
