I CAN CODE

Row by row

Row	Bulbs	Add the ‘on’ numbers	Character
1	01001001	64 + 8 + 1 = 73	I
2	00100000	32 = 32	a space
3	01000011	64 + 2 + 1 = 67	C
4	01000001	64 + 1 = 65	A
5	01001110	64 + 8 + 4 + 2 = 78	N
6	00100000	32 = 32	a space
7	01000011	64 + 2 + 1 = 67	C
8	01001111	64 + 8 + 4 + 2 + 1 = 79	O
9	01000100	64 + 4 = 68	D
10	01000101	64 + 4 + 1 = 69	E

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 = [
    "01001001",
    "00100000",
    "01000011",
    "01000001",
    "01001110",
    "00100000",
    "01000011",
    "01001111",
    "01000100",
    "01000101",
]
message = ""
for code in secret:
    number = int(code, 2)
    message = message + chr(number)
print(message)

When you run it, it prints:
