🔷 Hash Grid — Terminal ASCII Art in Python

A fun Python project that prints text as large ASCII art in the terminal using # and space characters — inspired by Tony Stark's iconic "Welcome, Mr. Stark" display.

🧠 How It Works

The Core Idea

Each letter is stored as a 2D grid (list of lists) where:

• # = a filled cell (part of the letter)
• (space) = an empty cell (background)

When printed row by row, these grids form large block letters in the terminal.

Example — The letter "A"

'A': [
    [" ", "#", "#", "#", "#", "#", " "],
    ["#", " ", " ", " ", " ", " ", "#"],
    ["#", " ", " ", " ", " ", " ", "#"],
    ["#", "#", "#", "#", "#", "#", "#"],
    ["#", " ", " ", " ", " ", " ", "#"],
    ["#", " ", " ", " ", " ", " ", "#"],
    ["#", " ", " ", " ", " ", " ", "#"],
]

Printed output:

 #####
#     #
#     #
#######
#     #
#     #
#     #

Printing Logic

The grid is printed by looping row by row (y), then column by column (x):

for y in range(height):
    for x in range(width):
        print(cell[x][y], end='')
    print()

This reads each row left-to-right and moves to the next line after each row — building the letter shape line by line.

🚀 How to Run

Make sure you have Python 3 installed.

Print "WELCOME MR. STARK":

python WELCOME_MR.STARK.py

Print any word using the full alphabet:

python EveryLetterIncluded.py

To change the word, edit the Sentence list inside the file:

Sentence = ['H', 'E', 'L', 'L', 'O']

See the grid coordinate theory:

python ThearyBehindIt.py

✏️ Customise It

Want to print your own word? Open EveryLetterIncluded.py and change this line:

Sentence = ['W', 'E', 'L', 'C', 'O', 'M', 'E']

All 26 letters (A–Z) are already defined in letter_dict, so you can spell out anything!

💡 What You'll Learn from This Project

• How 2D lists (grids) work in Python
• How nested for loops traverse a grid row by row
• How x/y coordinate systems map to array indices
• A creative way to render text as pixel art purely in the terminal

🛠️ Requirements

• Python 3.x
• No external libraries — pure Python!
