Хотя l oop неверно

Question

цель этого файла - запросить у пользователя значения, вычислить значения для различных целей и затем отобразить данные.

Всё работает кроме пока l oop. Предполагается, что значение порций уменьшается на go, если Grand_Weight_Mix_Total> 450.

Циклы while проверяют, превышает ли Grand_Weight_Mix_Total значение 450, если это так, тогда значение порций должно go down 1, а затем снова выполняется while l oop. L oop сломается, если стоимость порций станет ниже 450.

Answer 1

Я думаю, вы не поняли эту строку:

Grand_Weight_Mix_Total = float(Grand_Serving_Total_Weight * servings)

Эта строка означает, что Grand_Weight_Mix_Total является умножением Grand_Serving_Total_Weight * servings в данный момент, и он останется таким, пока вы не измените Grand_Serving_Total_Weight снова

Он не обновляется, когда вы меняете servings, вам нужно переназначить значение самостоятельно:

while (Grand_Weight_Mix_Total > 450):
        servings = servings - 1
        Grand_Weight_Mix_Total = float(Grand_Serving_Total_Weight * servings)
        print('Servings loop value', servings)

также обратите внимание, что я удаляю это

if Grand_Serving_Total_Weight <= 449:
     break

, что является избыточным из-за while l oop
