Coding Improvement

[MoreMoney]

Thank you for your help, but i have question i just need 6 atm digit for my homework should i decrase the range for faster completion time, or they dont make any different? Thank you

Also how to install numba properly?

It was more a example on how to speed up code a lot,i don't think you should give Numba code as a solution.
Without the ability to use external libraries or multiprocessing,and given the straightforward nature of a brute-force search,
there are limitations to how much the efficiency of this algorithm can be improved with pure Python.
Can clean it up a little.

from time import time

def find_pin(target_pin):
    for guess in range(1000000):
        if guess == target_pin:
            return True
    return False

def valid_pin(pin):
    return pin.isdigit() and len(pin) == 6

pin_input = input("Enter PIN: ")
start = time()
if not valid_pin(pin_input):
    print("Entered PIN is invalid")
else:
    target_pin = int(pin_input)
    if find_pin(target_pin):
        print(f"Found PIN in {time() - start} seconds.")
    else:
        print("PIN not found.")

Numba you install with pip.

Thank you very much for helping with my code, i'd really appreciate it
Now my code is better

Would you like to help me with my other coding i'm stuck with?
It's about logic improvement
