Set Expiration Date in python for specific keys

Question

***The Problem is that the Key "4255" always refreshes when i type it in the console and it never expires, and how can i set the expiration date for many keys and not only one.

I want the Key to expire in the 1 minute and store that information somewhere so it doesnt refresh everytime i reuse the key.***

import random
from datetime import datetime, timedelta

def generate_key():
    key = str("4255")
    expiration_time = datetime.now() + timedelta(days=0, minutes=1) #Key expires in 1 day and 30 minutes
    return key, expiration_time

def is_expired(expiration_time):
    return datetime.now() > expiration_time

correct_key, expiration_time = generate_key()

print("# Generated key", correct_key)

user_input = input("Enter your license Key:")

if expiration_time == timedelta:
    print("your425 Key expired", (expiration_time))

if user_input == correct_key:
    print("Successfully Loaded")

if user_input == correct_key:
    print("Expiration:",(expiration_time))

else:
    print("Key Expired")

input("Press any Key to close")

The Key Should start the expiration date at the first use and somewhere store the information.

Use dic to store key and expired time. This should work your code.

from datetime import datetime, timedelta
key_expiration_map = {}


def generate_key():
    key = str("4255")
    expiration_time = datetime.now() + timedelta(days=0, minutes=1) #Key expires in 1 day and 30 minutes
    return key, expiration_time

def is_expired(expiration_time):
    return datetime.now() > expiration_time


def validate_key(user_input):
    if user_input in key_expiration_map:
        expiration_time = key_expiration_map[user_input]
        if is_expired(expiration_time):
            print("Key Expired")
            return False
        else:
            print("Successfully Loaded")
            print("Expiration:", expiration_time)
            return True
    else:
        print("Invalid Key")
        return False

correct_key, expiration_time = generate_key()
key_expiration_map[correct_key] = expiration_time

print("# Generated key:", correct_key)

while True:
    user_input = input("Enter your license Key:")
    if validate_key(user_input):
        break

input("Press any Key to close")
