Need help with 3 errors when running script

[pythoncoder999]

So I got this bot script for reddit that I want to use for some automation for my business, it works up to the point of login to reddit user but fails at sending message, I get these 3 errors:


Config.py contents:(fill in apostophies with apropriate info)

username    = ' ' #reddit username of your account
password            = ' ' #reddit password of your account
messagesfile        = 'example.txt ' #file with messages 1 per line
usersfile           = 'example2.txt ' #file with users to DM 1 per line 

The two txt files contain messages and test user.

Now this is the code main python file:

import time
import string
import requests
from bs4 import BeautifulSoup
import sys
from random import randint
from config import *

def redditlogin(username, password,c):

    USER                = username

    OP                  = 'login-main'
    RENDERSTYLE         = 'html'
    ACTION              = 'sub'

    loginpost           = 'https://www.reddit.com/api/login/'+USER
    homeurl             = 'https://www.reddit.com'


    print ("[+]Logging in as "+USER+"...")

    if 'reddit_session' in str(login.headers):
        print ('[+]Successfully logged into account '+USER)
    else:

def sendmessages(userslist, messagelist,c):

                MESSAGE_LIST.append(message)

        USER_LIST.append(user)

        soup = BeautifulSoup(r,'html.parser')
        MODHASH = soup.find('input',{'name':'uh'})['value']
        REDDIT_SESSION = c.cookies['reddit_session']

        params = (
            ('app', 'res'),
                )

        data = [

            ('text',MESSAGE_TEXT),
            ('to', MESSAGERECIEVER),
                ]

def main():
    with requests.session() as c:

        try:
            userslist = open(usersfile,'r')
        except IOError:
            sys.exit("[-]Invalid user list!")

        try:
            messagelist = open(messagesfile,'r')
        except IOError:
            sys.exit("[-]Invalid message list!")

        redditlogin(username,password,c)
        sendmessages(userslist,messagelist,c)


if __name__ == '__main__':
    main()

All help is much apreciated. I am not experienced with python if anyone could help me get this script working

The code lines shown are the line numbers that were executed prior to receiving the error.
So in Your case, the sequence is: line 89 (main()), then line 85, and finally line 54 where the error actually occurred.

The code of that line is then shown, and the error message explains that the subscript used is the issue.

Looking at that, you can't use a string 'value' as an index. use without quotes, which is the variable name.

thanks for the tip, but it says value is not defined

try removing ['value'] entirely.
I don't know what that is supposed to be.
this part:MODHASH = soup.find('input',{'name':'uh'})
says to find a tag named input, with a name='uh' attribute.
I can't see the page you're scraping, so it's difficult.
