Answer: Pixel Puzzle #73

The hidden picture is a robot!

The finished pixel picture: a robot.
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 = [
    "00011000",
    "00022000",
    "03333330",
    "03433430",
    "03355330",
    "03333330",
    "00666600",
    "00050000",
]
symbols = " #@*o+="

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

When you run it, it prints:

   ##
   @@
 ******
 *o**o*
 **++**
 ******
  ====
   +
