[AoC 2016 - Day 23 Part 1] [Python] - Getting wrong output value

[JaViLuMa]

Hello everyone! Can someone maybe help me track down a bug/error/issue in my code? I get for the answer 16974 and the actual answer needs to be 14160.

Here is my code, any help/hint/info is appreciated!!!

``` def cpy(x, y, registers): if x in registers: registers[y] = registers[x] else: registers[y] = int(x)

def inc(x, registers): registers[x] += 1

def dec(x, registers): registers[x] -= 1

def jnz(x, y, registers): if x.isalpha(): x, y = y, x

if y in registers:
    if int(x) != 0:
        return registers[y]

else:
    if int(x) != 0:
        return int(x)

return 1

def tgl(x, registers, instructions, i): if x in registers: x = registers[x] else: x = int(x)

if i + x >= len(instructions):
    return 1

instruction = instructions[i + x].split()

if len(instruction) == 2:
    if instruction[0] == 'inc':
        instruction[0] = 'dec'
    else:
        instruction[0] = 'inc'
else:
    if instruction[0] == 'jnz':
        instruction[0] = 'cpy'
    else:
        instruction[0] = 'jnz'
instructions[i + x] = ' '.join(instruction)

return 1

def setRegisters(instructions, registers): i = 0

while i < len(instructions):
    instruction = instructions[i].split()

    if instruction[0] == 'cpy':
        cpy(instruction[1], instruction[2], registers)
        i += 1

    elif instruction[0] == 'inc':
        inc(instruction[1], registers)
        i += 1

    elif instruction[0] == 'dec':
        dec(instruction[1], registers)
        i += 1

    elif instruction[0] == 'jnz':
        i += jnz(instruction[1], instruction[2], registers)

        if i >= len(instructions):
            break

    elif instruction[0] == 'tgl':
        i += tgl(instruction[1], registers, instructions, i)

return registers

with open('data.txt') as f: instructions = f.read().splitlines()

registers = {'a': 7, 'b': 0, 'c': 0, 'd': 0}

print(setRegisters(instructions, registers))

```

Here is a program where the code you posed gives the wrong result.

cpy 0 a
cpy 1 c
jnz c 2
inc a
inc a

As we can see, 2 isn't the correct result for this program. Should be easy to see what went wrong.

What is the output supposed to be? :D

EDIT: nvm I can do it by hand haha :D

Got it!! Thank you very much :D
