I’m trying to make a lottery system in Python using the following code:

failed = True
passed = False
number_of_tickets = []
ticket_num = []
ticket_cost = int(10)
ticket_cost_sum = 0
randomly_generated_num = []
final_ticket = []

ticket_sum_inquiry = (int(input("Enter number of tickets: ")))
ticket_sum_inquiry
print (ticket_sum_inquiry)

print ("It will cost", ticket_sum_inquiry*ticket_cost, "dollars for these tickets.")

import random
def randint(min=1,max=100):
    randomly_generated_num = random.randint(min,max)
    return randomly_generated_num

randint()
ticket_num.append(randomly_generated_num)
   

Proceed = input('Would you like to continue? enter "y" for yes, enter "n" no: ' )
if Proceed.lower() == "y":
  print ("Great, here are your tickets with their numbers:")
  for tickets, numbers in zip(ticket_sum_inquiry, ticket_num):
    print(tickets, ':', {randint(numbers)} )
elif Proceed.lower() == "n":
    print ("Goodbye")
else:

As you can see, the code is incomplete, as I’ve yet to implement the winning numbers for the lottery. However, along the way, I encountered a problem when trying to give the user their **tickets **along with generating the corresponding numbers to those tickets:

 for tickets, numbers in zip(ticket_sum_inquiry, ticket_num):
    print(tickets, ':', {randint(numbers)} )

Whenever I try to run this, Python returns:
TypeError: ‘int’ object is not iterable
