Brainfuck Python interpreter (ChatGPT)

Here is a Brainfuck interpreter in Python. Edited from the Numberfuck interpreter which was coded by ChatGPT. Still is optimized for everything, including printing the full lyrics of the song Never Gonna Give You Up.

def interpret():
    code = input("Enter Brainfuck code: ")
    memory = [0] * 30000
    pointer = 0
    output_string = ""
    code_length = len(code)
    code_pointer = 0

    loop_stack = []

    commands = {
        '>': lambda: nonlocal_pointer('+'),
        '<': lambda: nonlocal_pointer('-'),
        '+': lambda: increment_memory(),
        '-': lambda: decrement_memory(),
        '.': lambda: output_to_string(),
        ',': lambda: take_input(),
        '[': lambda: start_loop(),
        ']': lambda: end_loop()
    }
