Nested Loops - cinema tickets

Здравейте,

имам затруднения с решението на задачата. Може да се каже, че тези затруднения не са с конкретната задача , а по-скоро с принципа който използвам. Та накратко пиша си нещата, проверките излизат, но само ако имам един филм. Не се сещам как да почна отначало цекъла. ако някой има възможност да погледне кода.

film = input()
capacity = int(input())
ticket_type = ""
counter_standart = 0
counter_kid = 0
counter_student =0
ticket_counter = 0

while film != "Finish":

    while ticket_type != "End":
        ticket_type = input()
        if ticket_type == "standard":
            counter_standart += 1
        elif ticket_type == "kid":
            counter_kid += 1
        elif ticket_type == "student":
            counter_student += 1

    ticket_type = input()
    ticket_counter = counter_standart + counter_kid + counter_student
    print(f"{film} - {ticket_counter / capacity * 100}% full.")
    print(f"Total tickets:{ticket_counter}")
    print(f"{counter_student / ticket_counter * 100:.2f}% student tickets.")
    print(f"{counter_standart / ticket_counter * 100:.2f}% standard tickets.")
    print(f"{counter_kid / ticket_counter * 100:.2f}% kids tickets.")

Ето и едно мое решение, което дава 100/100:

movie = input()

ticket1 = 0
ticket2 = 0
ticket3 = 0
sum_tickets = 0

while movie != "Finish":
    empty_places = int(input())
    count_places = 0
    while count_places < empty_places:
        ticket = input()
        if ticket == "End":
            break
        if ticket == "student":
            ticket1 += 1
            count_places += 1
        elif ticket == "standard":
            ticket2 += 1
            count_places += 1
        elif ticket == "kid":
            ticket3 += 1
            count_places += 1
    count_places = (count_places / empty_places) * 100
    print(f"{movie} - {count_places:.2f}% full.")
    movie = input()

if movie == "Finish":
    sum_tickets = ticket1 + ticket2 + ticket3
    ticket1 = (ticket1 / sum_tickets) * 100
    ticket2 = (ticket2 / sum_tickets) * 100
    ticket3 = (ticket3 / sum_tickets) * 100
    print(f"Total tickets: {sum_tickets}")
    print(f"{ticket1:.2f}% student tickets.")
    print(f"{ticket2:.2f}% standard tickets.")
    print(f"{ticket3:.2f}% kids tickets.")
