Question

我正在尝试猜测数字游戏，它会选择一个随机数，然后如果你选择了正确的按钮，它说你是正确的，如果你选错了它就说不正确。

print("~Guess the Number~")
print("Pick any number")

topFrame=Frame(root)
bottomFrame=Frame(root)

topFrame.pack(side=TOP)
bottomFrame.pack(side=BOTTOM)

#Random Number
import random
b=(random.randint(1,4))

#Functions
def number1(event,b):
if b==1:
    print("You guessed the correct number")
else:
    print("Not the correct number")

def number2(event,b):
if b==2:
    print("You guessed the correct number")
else:
    print("Not the correct number")

def number3(event,b):
if b==3:
    print("You guessed the correct number")
else:
    print("Not the correct number")

def number4(event,b):
if b==4:
    print("You guessed the correct number")
else:
    print("Not the correct number")

#Where the buttons are
button1=Button(topFrame,text="1")
button2=Button(topFrame,text="2")
button3=Button(topFrame,text="3")
button4=Button(topFrame,text="4")
button5=Button(bottomFrame,text="Quit")

#Binding the buttons
button1.bind("<Button-1>",number1)
button1.pack(side=LEFT)

button2.bind("<Button-2>",number2)
button2.pack(side=LEFT)

button3.bind("<Button-3>",number3)
button3.pack(side=LEFT)

button4.bind("<Button-4>",number4)
button4.pack(side=LEFT)

button5.pack()

它给了我：

__init__.py", line 1550, in __call__
return self.func(*args)
TypeError: number1() missing 1 required positional argument: 'b'

我对python还不太了解：/

你的函数需要两个参数

def number1(event, b):

但bind()始终只发送一个 - event。

您可以使用lambda发送更多参数

 bind(`<Button-1>`, lambda event: number1(event, b))

BTW <Button-1>，<Button-2>等等意味着鼠标按钮

<Button-1>是鼠标左键 <Button-2>是鼠标中键 <Button-3>是鼠标右键。

BUtton()有参数command=来分配函数，它不会发送event

 button1 = Button(topFrame, text="1", command=lambda:number1(b))

 def number1(b):
    # ...

但你可以为所有按钮创建一个功能

def check_number(b, button_number):
    if b == button_number:
         print("You guessed the correct number")
    else:
        print("Not the correct number")

button1 = Button(topFrame, text="1", command=lambda:check_number(b, "1"))
button2 = Button(topFrame, text="2", command=lambda:check_number(b, "2"))
button3 = Button(topFrame, text="3", command=lambda:check_number(b, "3"))
button4 = Button(topFrame, text="4", command=lambda:check_number(b, "4"))
