How to make my code work with asyncio?

[DevinGP]

Here is my code:

import asyncio
import aiohttp
import urllib
import webbrowser
from bs4 import BeautifulSoup
import re

global link
link = ""

async def get(url):

    async with aiohttp.ClientSession() as session:
        async with session.get(link) as resp:
            return await resp.text()

async def main():

    address = 'https://google.com/search?q='
    # Default Google search address start
    file = open( "OCR.txt", "rt" )
    # Open text document that contains the question
    word = file.read()
    file.close()

    myList = [item for item in word.split('\n')]
    newString = ' '.join(myList)
    # The question is on multiple lines so this joins them together with proper spacing

    qstr = urllib.parse.quote_plus(newString)
    # Encode the string

    newWord = address + qstr
    # Combine the base and the encoded query

    text = await get(newWord)

    answers = open("ocr2.txt", "rt")

    ansTable = answers.read()
    answers.close()

    ans = ansTable.splitlines()

    ans1 = str(ans[0])
    ans2 = str(ans[2])
    ans3 = str(ans[4])

    ans1Score = 0
    ans2Score = 0
    ans3Score = 0

    links = []

    soup = BeautifulSoup(text, 'lxml')

    for r in soup.find_all(class_='r'):

        linkRaw = str(r)

        link = re.search("(?P<url>https?://[^\s]+)", linkRaw).group("url")

        if '&' in link:

            finalLink = link.split('&')
            link = str(finalLink[0])

        links.append(link)

    coros = [
        process_single_g(g)
        for g
        in soup.find_all(class_='g')
    ]

    results = await asyncio.gather(*coros)

    for res in results:
        ans1Score, ans2Score, ans3Score = res

        print(' ')
        print('-----')
        print(ans1+": "+str(ans1Score))
        print(ans2+": "+str(ans2Score))
        print(ans3+": "+str(ans3Score))
        print('-----')

async def process_single_g(g):

    for g in soup.find_all(class_='g'):

        webBlock = str(g).lower()

        ans1Tally = webBlock.count(ans1)
        ans2Tally = webBlock.count(ans2)
        ans3Tally = webBlock.count(ans3)

        ans1Found = True
        ans2Found = True
        ans3Found = True

        if  ans1 in webBlock:

            ans1Score += ans1Tally

        else:

            ans1Found = False

        if ans2 in webBlock:

            ans2Score += ans2Tally

        else:

            ans2Found = False

        if ans3 in webBlock:

            ans3Score += ans3Tally

        else:

            ans3Found = False

        if (ans1Found == False) and (ans2Found == False) and (ans3Found == False):

            print("Searching Link!")

            try:

                searchLink = str(links[0])

                if searchLink.endswith('pdf'):
                    pass

                else:

                    response2 = requests.get(searchLink)
                    soup2 = BeautifulSoup(response2.text, 'lxml')

                    for p in soup2.find_all('p'):

                        extraBlock = str(p)

                        extraAns1Tally = extraBlock.count(ans1)
                        extraAns2tally = extraBlock.count(ans2)
                        extraAns3Tally = extraBlock.count(ans3)

                        if ans1.lower() in extraBlock.lower():

                            ans1Score += extraAns1Tally

                        if ans2.lower() in extraBlock.lower():

                            ans2Score += extraAns2Tally

                        if ans3.lower() in extraBlock.lower():

                            ans3Score += extraAns3Tally

            except:

                pass

        if len(links) > 0:

            links.pop(0)

        else:

            pass

        text2 = await get(searchLink)

if __name__ ==  '__main__':
    loop = asyncio.get_event_loop()
    try:
        loop.run_until_complete(main())
    finally:
        loop.run_until_complete(loop.shutdown_asyncgens())
        loop.close()

Here is my error:

I am sure there are many things wrong with it, as this was another users suggestion to make my code asynchronous. I am really lost on how to use aiohttp and asyncio, but my program that runs synchronously works perfectly. So the only trouble I am having is converting it to scrape all of the "g" classes at the same time instead of doing them one at a time down the line. There will always be 10 of them, as the "g" class is a google search result. I have looked over the documents and have searched SO but can not find anyone that has been trying to do the same thing as me. If anybody could provide some assistance it would be greatly appreciated. I am sorry if this code is really messed up, I am really lost so ANY kind of help and clarification (or even better, just showing me how it is done so I can actually see what the proper code looks like to learn) is massively appreciated. I have posted and looked on SO before but nobody seems to have posted my kind of situation before. Thanks for reading!
