Sentiments "tweets" elif statement error

Question

Trying to run this, but getting an error at the very bottom "elif" statement while trying to set the colour saying it is invalid syntax. I don't know why. Also, am I doing this problem correctly? I think I have done everything for tweets but I am not sure

#!/usr/bin/env python3
import sys
from helpers import get_user_timeline
from anaylzer import analyze
from termcolor import colored
import nltk
import os

def main():
    #set screen name to argv1
    screen_name = sys.argv[1].strip("@")

    #set absolute paths to the words lists
    positivestxt = os.path.join(sys.path[0], "positive-words.txt")
    negativestxt = os.path.join(sys.path[0], "negative-words.txt")

    #ensure proper usage
    if len(sys.argv) != 2:
        print("Usage: ./tweets @screen_name")
        return 1

    #ensure screen name is valid
    elif get_user_timeline(screen_name) == None:
        print("screen name not valid (does not exist or may be a private account)")
        sys.exit


    else:
        #get user timeline tweets, 50 of them from the inputed screen name
        tweets = get_user_timeline(screen_name, 50)

        #instantiate analyzer with inputs positivestxt and negativestxt
        analyzer = Analyzer(positivestxt, negativestxt)

        #for each word in tokenslist analze the score and print appropriate colour
        tokenslist = nltk.tokenize.TweetTokenizer(tweets)
        for word in tokenslist:
            wordscore = analyzer.analyze(word)

            if wordscore > 0.0:
                print(colored(wordscore + word, "green")

            elif wordscore < 0.0:
                print(colored(wordscore + word), "red")

            else:
                print(colored(wordscore + word, "yellow")


if __name__ == "main":
    main()

Answer 1

Looks like unbalanced parentheses in the line above the elif.
