Проблема Python с def, ошибка с переменной внутри def, переменная не работает в операторе if

Question

Я сделал def roomidea(test) со входами внутри, я думаю, что сделал return правильно.Теперь под первым оператором if у меня есть sBedsize, sRoomview, sVehicle, iRoomnum, iNights = roomidea(test), поэтому он читает функцию.Проблема в том, что когда я запускаю код, он отображает

sBedsize не определено

, хотя у меня все это в выражении if.Почему это не работает?

Я работал над этим проектом некоторое время, теперь я думаю, что мой второй def price(test2) работает, но я еще не уверен, так как первый def является основной проблемойДо сих пор я был бы признателен за любые советы или помощь или что-нибудь, что может помочь мне решить или узнать, как решить эту проблему.

Теперь у меня также есть большая проблема, что я использую много переменных во второй def, то есть я использую переменные для решения других переменных, таких как dTotalqav и имеющих dPrice1, dPrice5, dResortfee1 и dResortfee2 внутри одного и того же def.Из-за этого это будет правильно или просто создаст другую ошибку?

Я запускаю это в PyCharm, на случай, если это уместно.

Также, наконец, для времени импорта, а затемtime.sleep (5), затем print (test) потом, я использую его, чтобы он перепечатывал исходные данные, чтобы они могли изменить свои входы и, возможно, если они выбрали «Queen Standard Yes 1 1», но они допустили ошибку, которую ониможете набрать no и изменить их ввод на что-то вроде «King Standard Yes 1 1». В любом случае, извините за этот быстрый вопрос, но это основные проблемы, с которыми я сталкиваюсь.

Answer 1

Вам нужно вызвать функцию и присвоить эти переменные до , вы можете запросить их в своем выражении if.

Вот упрощенный пример:

def foo():
    # These variables only exist inside the function
    one = 1
    two = 2
    three = 3

    # This doesn't cause them to exist outside of the function; it "gives them"
    # as a result of calling the function later
    return one, two, three

# a, b, and c don't exist yet so I can't use them in an if statement here

# This is where we run the code contained in the function foo and bind the
# returned values to variables (they can be named differently, here we use a,
# b, and c)
a, b, c = foo()

# a, b, and c now exist as variables in the main program and they hold the values
# that were returned from the function. Now we can use them in an `if` statement, e.g.
if a or b or c:
    print('Success')
