Computer science can you help me with the last part of the code after mentionedWords.

[shirleylam852]

def cleanedup(s):
    alphabet='abcdefghijklmnopqrstuvwxyz@_0123456789'
    cleantext= ''
    for character in s.lower():
           if character in alphabet:
                 cleantext+= character
           else:
                 cleantext+=' '
    return cleantext

import os

def contains(filename):
    counts={}
    mentionedWords=[]
    with open(filename) as file:
             for word in cleanedup(line).split():
                if filename[2] =='@':
                    if word in counts:
                        counts[word]+=1
                    else:
                        counts[word]=1
                print("fn=",filename)

    for word in counts:
           mentionedWords.append([counts[word],word])

    for filename in os.listdir('.'):
        if filename[-3:]=='.tweets':
            contains (filename)
                
    mentionedWords.sort()

    
    for item in mentionedWords[-3:]:
        print ('  ', item [1], item[0])

Okay, my code as of right now. I'm missing something in between line 32-36.
The only hint I was given to fix my code was this:

To print the username followed by its count, remember that each item in mentionedWords in your program is a list, and the unit 4 "Learn" PDF starting on p. 8 explains that items in a list can be accessed by index. For example, suppose you have a list x = [123, 'abc']. Then, x[0] is 123 and x[1] is 'abc'. If you want to print the second item in the list followed by the first item, i.e. abc followed by 123, you would just do print(x[1], x[0]). So, in your program, write a loop that goes through each item of the slice that represents the 3 most frequently mentioned usernames in mentionedWords.

If code was written correctly output should run like this:
