Overview and Requirements

Write a program (ascii_art_text.py) to generate files containing words represented by ASCII art. I have used this website to generate 26 files each containing ASCII art for a capital letter of the alphabet (there are 26 letters in the alphabet). For this assignment, you will need to download a zip file containing these 26 files: stars.zip. (https://raw.githubusercontent.com/gsprint23/cpts111/master/progassignments/files/stars.zip ) Unzip this stars.zip into a folder called stars. Take a look at A.txt, pretty cool huh? Check out the different fonts available from the website I used, they are awesome!

Program Details

The program should perform the following steps:

Populate a list of file names for each letter text file. To do this, use the os module's function called listdir(<string path to directory>) that returns a list of the files in a particular directory.

Generate a dictionary, called letter_art, of key:value pairs where each key is a letter string and each value is a list of strings representing the lines of the corresponding letter's ASCII art. For example, the key "A" maps to the list of strings representing the lines in A.txt. Recall: <file object>.readlines()returns a list of string lines in a <file object>.

Update each ASCII art value in letter_art such that the ASCII art is composed of the same letter the ASCII art represents. For example, letter_art["A"] should store the ASCII art for A made of "A"s and "a"s. For an example, please see the output below.

Prompt the user for a word and store the user-entered string in a variable named word.

Convert word to all uppercase.

For each letter in word, write the corresponding ASCII art letter (from the letter_art dictionary) horizontally to an output file word_art.txt. Place a space line between ASCII art letters.

Starter Code

Here is some starter code to read in the ASCII art from the files. If you are running a unix-based operating system (e.g. Mac, Linux distributions), you will need to replace the back slashes with forward slashes in the file names.

Note: This starter code should be in a python source file, ascii_art_text.py, in the same folder (e.g. Bonus_PA) containing the stars folder. So the directory structure looks like the following:

Explanation / Answer

import os

def gen_file_contents(file_list: list):
    letters = list()

    for file in file_list:
        with open("stars\" + file, "r") as file:
            lines = file.read().splitlines()
            letters.append(lines)

    return letters

def gen_letter_dict(letter_list: list) -> dict:
    letter_dict = dict()
    letters = [chr(i).upper() for i in range(97, 123)]
    for i in range(len(letters)):
        letter_dict[letters[i]] = letter_list[i]

    return letter_dict

def get_user_word() -> str:
    return input("Enter a word to get converted to ASCII art. >> ").upper()

def print_ASCII_art(word: str, letter_art: dict) -> None:
    values = [chr(i).upper() for i in range(97, 123)]

    for letter in word:
        word_val = ord(letter) # W = 87, S = 83, U = 85
        for line in letter_art.get(chr(word_val)):
            print(line)

def main():
    file_list = os.listdir("stars")

    letters = gen_file_contents(file_list) # A list of lists.
    letter_art = gen_letter_dict(letters)

    word = get_user_word()

    print_ASCII_art(word, letter_art)

main()
