Question

For Phton language 3.

You are to create a decoder program that takes a tweet as input and turns it into an English sentence. A tweet will contain common acronyms and abbreviations, and your program will need to have a way to decode them (dictionary).

For example) “lol” => “laughing out loud”, “brb” => “be right back”
Provided is a file with common tweet abbreviations and associated meanings, your program is to use this

csv file (tweet_decoder.csv) to create its dictionary.

Start by creating a framework for the program that contains a dictionary with a few abbreviations

such as
decoder = { “brb” : ”be right back”, ”b4” : ”before” ...}

Ask for a user to input a tweet.

Lookup abbreviations within the tweet, decode and replace them.

Print out the decoded string.

Offer the option to run again.

Your program will need to open up the “tweet_decoder.csv” file. Make sure that this file is

copied into the same directory where your python file is saved.

Review slide 16 from week 12 (part1, Record example 2) as a reference.

Each line of the CSV file represents a key and a value pair – These needs to be added to the

dictionary.

# pastebin link for code:https://pastebin.com/bFF6txL4

word_dict = {}

with open("tweet_decoder.csv", "r") as fh:
    for line in fh:
        (abbr, meaning) = line.split(",", 1)
        print(abbr, meaning)
        word_dict[abbr] = meaning.strip()
        word_dict[abbr.lower()] = meaning.strip()

def tweet_decoder(tweet):
    tweet_split = tweet.split()
    result_tweet = []
    for tweet in tweet_split:
        if tweet in word_dict:
            result_tweet.append(word_dict[tweet])
        else:
            result_tweet.append(tweet)
    return " ".join(result_tweet)

tweet = input("Enter a tweet: ")
tweet = tweet_decoder(tweet)

print("Decoded tweet: " + tweet)
