“NoneType”错误

Question

我是新来的Python，我看其他的代码，但不知道如何从矿井中删除nonetype错误，

tutorial = input("Do you want to do the tutorial? 1 is yes and 0 is no, this will be the same for everything") 
if tutorial <1: 
    print("That isn't valid") 
if tutorial>0: 
    print("That isn't valid") 
if tutorial == 1: 
    print("In battle you can use either sword, magic or items. Sword damage will be between your minimum and maximum damage, magic will be constant and can be used to heal or attack, items can be used to boost attack, restore health or armour") 

我得到这个错误：

Traceback (most recent call last): 
    File "<string>", line 250, in run_nodebug 
    File "C:\Users\Bas\Desktop\Game.py", line 50, in <module> 
    tutorial = input("Do you want to do the tutorial? 1 is yes and 0 is no, this will be the same for everything") 
TypeError: 'NoneType' object is not callable 

继承人的全码：

playerhealth = 100 
playerlow = 10 
playerhigh = 30 
playerarmour = 50 
playermagic = 20 
level = 0 
xptonextlevel = 200 
itemuse = 0 

rookhealth = 100 
rooklow = 10 
rookhigh = 20 
rookarmour = 100 

medichealth = 150 
mediclow = 10 
medichigh = 30 
medicarmour = 50 

rushhealth = 20 
rushlow = 10 
rushhigh = 10 
rusharmour = 30 

drillerhealth = 30 
drillerlow = 50 
drillerhigh = 80 
drillerarmour = 20 

dragonhealth = 200 
dragonlow = 150 
dragonhigh = 250 
dragonarmour = 150 
dragonmagic = 100 
dragonl = 45 

godhealth = 300 
godlow = 250 
godhigh = 350 
godarmour = 250 
godmagic = 200 
godl = 50 

magehealth = 100 
magearmour = 0 
magemagic = 50 
magel = 10 

tutorial = input("Do you want to do the tutorial? 1 is yes and 0 is no, this will be the same for everything") 
if tutorial <1: 
    print("That isn't valid") 
if tutorial>0: 
    print("That isn't valid") 
if tutorial == 1: 
    print("In battle you can use either sword, magic or items. Sword damage will be between your minimum and maximum damage, magic will be constant and can be used to heal or attack, items can be used to boost attack, restore health or armour") 

se = input("Input 1 for story or 0 for endless")

因为标识符input已分配值0123你得到这个错误。在您的代码中的某处，必须执行以下行。

input = None 

NoneType是单恒定None的类型。 如果试图这样做你会得到相同的错误：

>>> None("Do you want to do the tutorial?") 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
TypeError: 'NoneType' object is not callable 

Python并不妨碍您覆盖内置函数用新值。有时重新定义例如功能print会很有用。但在正常情况下，使用input，list,int等作为变量名称是一个糟糕的主意，因为这会导致诸如此类的错误。

您可以通过使用字典而不是声明很长的变量列表来减少意外覆盖标识符的可能性。

gamestate = { 
    'playerhealth': 100, 
    'playerlow': 10, 
    'playerhigh': 30, 
    'input': None, 
    'else': 42, 
    ... 

您可以使用任何字符串作为字典键，而不用担心影子内建。
