Answer: Pixel Puzzle #65

The hidden picture is a smiley face!

The finished pixel picture: a smiley face.
Here’s what the colours make.

The picture as Python

Here is the same picture stored as numbers in a Python list. The program reads each number and prints a symbol for it, so you can see the picture appear in the Python shell.

picture = [
    "00111100",
    "01111110",
    "11211211",
    "11111111",
    "12111121",
    "11222211",
    "01111110",
    "00111100",
]
symbols = " #@"

for row in picture:
    line = ""
    for number in row:
        line = line + symbols[int(number)]
    print(line)

When you run it, it prints:

  ####
 ######
##@##@##

#@####@#
