ASCII Text Art is a loops/file I/O/strings/lists/dictionaries programming assignment for a CS0/CS1 course. For this assignment, students read in 26 text files, where each files stores ASCII art for a letter of the upper case alphabet. For example, A.txt stores ASCII art for the letter A, B.txt stores ASCII art for the letter B, and so on. The ASCII art for each letter is represented in the program as a list of strings, one string per line in the file. Collectively, all 26 lists are stored in a dictionary as letter (key) and list (value) pairs. Once loaded into the dictionary, the assignment requires students to modify the ASCII art by replacing characters. Lastly, the program prompts the user for a string of letters and the program writes the string to a file using the modified ASCII art.
