I really need help with this Python program!!!!!!!! Please help me :(

You will design a computer program using sequential, conditional, looping, and functions. You are not allowed to use the built-in write() function in this assignment.

First, choose 6 letters to draw using ASCII art. Now, write a program to draw a different word to the screen in ASCII art, each time the user enters a string containing any of the 6 letters you chose to support. I would highly suggest you use graphing paper or some kind of paper to design what will be needed to get the letters to be drawn in ASCII art.

You can have the ASCII art be any variation of upper and lower case letters, but you must accept strings of both from the user. You must prompt the user for a string of letters and draw the ASCII art vertically to the screen that corresponds to the user’s string. You need to continue to do this until the user wants to quit. You also need to make sure you ask the user for a different string, if their string contains letters you do not support in your program.

Solution

Here is your program, just need to generalize it :
