3	01000001	64 + 1 = 65	A
4	01000111	64 + 4 + 2 + 1 = 71	G

Crack it with Python

Python can do the adding for you. int(code, 2) reads a string of 1s and 0s as a binary number. Then chr() turns the number into its character.

secret = [
    "01000100",
    "01010010",
    "01000001",
    "01000111",
    "01001111",
    "01001110",
]
message = ""
for code in secret:
    number = int(code, 2)
    message = message + chr(number)
print(message)

When you run it, it prints:

DRAGON
