A gift card generator using the python secrets module and timestamp to generate cryptographically strong random gift card codes

giftCardGenerator.py

import time
import string
import secrets


'''
The secrets module is used for generating cryptographically strong random numbers suitable for managing data such as passwords, 
account authentication, security tokens, and related secrets.

def generateGiftCardCodes():
     seconds = time.time()
     unix_time_to_string = str(seconds).split('.')[0] #time.time() generates a float example 1596941668.6601112
     alphaNumeric = string.ascii_uppercase + unix_time_to_string
     firstSet = ''.join(secrets.choice(alphaNumeric) for i in range(4))
     secondSet = ''.join(secrets.choice(alphaNumeric) for i in range(4))
     thirdSet = ''.join(secrets.choice(alphaNumeric) for i in range(4))

     giftCardCode = firstSet + "-" + secondSet + "-" + thirdSet
    #  return giftCardCode
    
     print(giftCardCode)


print("Please enter the number of gift codes you want to generate")
num = int(input("Enter: "))
for i in range(num):
    generateGiftCardCodes()

This is a much better approach:

import secrets
import string


def gen_rnd_string(
    n: int = 4
) -> str:
    return ''.join(
        secrets.choice(
            string.ascii_uppercase + string.digits
        )
        for _ in range(n)
    )


def generate_gift_card(
    n: int = 4
) -> str:
    return "-".join(
        gen_rnd_string() for _ in range(n)
    )


if __name__ == "__main__":
    gift_code = generate_gift_card()

    print(gift_code)
