如果在Python中的语句

Question

好吧，这应该是一个相对容易的。当我运行程序时，我注意到Damage整数没有传递给Damage_Applied if语句。它会在Damage_Applied整数之前正常工作。如何将Damage整数下载到第二个if语句，还是应该重写整个部分？

elif menu_option == 2: 
    print "Damage Taken?"
    Damage = int(raw_input(prompt))
    print "Where would you like damage to be applied?"
    print "1. HP"
    print "2. CP"
    print "3. Armor"

    Damage_Applied = int(raw_input(prompt))

    if Damage_Applied == 1:
        HP = HP - Damage
    elif Damage_Applied == 2:
        CP = CP - Damage
    elif Damage_Applied == 3:
        Armor = Armor - Damage

Answer 1

您需要定义： -

• HP
• CP
• 护甲

在Python中，要从另一个值中减去一个值，您需要同时拥有这两个值。目前，在您的代码中，HP = None，这不是数值，因此HP需要定义为数值（这同样适用于CP和Armor），因此我们将其定义为100，如下所示： -

HP = 100

而且，我们还需要使用CP和Armor这样做，所以，像这样： -

CP = 100
Armor = 100

显然，您可以将100s更改为您喜欢的任何内容，它仍然有效。

完整的代码看起来像这样： -

Python 3.x

elif menu_option == 2:
    HP= 100 #Defining 'HP'
    CP = 100 #Defining 'CP'
    Armor = 100 #Defining 'Armor'
    #For future reference, make sure ALL variables used in an 
    #if statement are defined before using them

    print("Damage Taken?")
    Damage = int(input(prompt))
    print("Where would you like damage to be applied?")
    print("1. HP")
    print("2. CP")
    print("3. Armor")

    Damage_Applied = int(input(prompt))

    if Damage_Applied == 1:
        HP = HP - Damage
    elif Damage_Applied == 2:
        CP = CP - Damage
    elif Damage_Applied == 3:
        Armor = Armor - Damage

Python 2.x

elif menu_option == 2:
    HP= 100 #Defining 'HP'
    CP = 100 #Defining 'CP'
    Armor = 100 #Defining 'Armor'
    #For future reference, make sure ALL variables used in an 
    #if statement are defined before using them

    print "Damage Taken?"
    Damage = int(raw_input(prompt))
    print "Where would you like damage to be applied?"
    print "1. HP"
    print "2. CP"
    print "3. Armor"

    Damage_Applied = int(raw_input(prompt))

    if Damage_Applied == 1:
        HP = HP - Damage
    elif Damage_Applied == 2:
        CP = CP - Damage
    elif Damage_Applied == 3:
        Armor = Armor - Damage

该代码应该有效。如果您需要任何帮助，请直接通过＆＃39; aaron@dibdibguy.com'与我联系;
