可以通过单击Python tkinter中的按钮来更新i的值

在此点击器代码中，我找不到这个错误。 I变量不是通过单击“单击”按钮来更新。如果您发现错误，请通知我。谢谢你！

from tkinter import *

root = Tk()
i = 0

def numberchanger():
    i = i + 1

clicker = Button(text="click", bg="red", fg="green", font="Arial 20 bold", command=numberchanger)
clicker.place(x=600, y=400)
widget.title("Clicker")
clicknumber = Label(text=i, fg="blue", font="Arial 50 bold")
clicknumber.place(x=600, y=200)



root.mainloop()

i can't find that mistake in this clicker code. The i variable is not updating by clicking the "click" button. Please inform me if you find the mistake. Thank you!

from tkinter import *

root = Tk()
i = 0

def numberchanger():
    i = i + 1

clicker = Button(text="click", bg="red", fg="green", font="Arial 20 bold", command=numberchanger)
clicker.place(x=600, y=400)
widget.title("Clicker")
clicknumber = Label(text=i, fg="blue", font="Arial 50 bold")
clicknumber.place(x=600, y=200)



root.mainloop()

添加全局i之后def numberChanger（）：

from tkinter import *

root = Tk()
i = 0

def numberchanger():
    global i
    i = i + 1
    print(i)
    clicknumber.config(text=i)


clicknumber = Label(text=i, fg="blue", font="Arial 50 bold")
clicknumber.place(x=600, y=200)

clicker = Button(text="click", bg="red", fg="green", font="Arial 20 bold", command=numberchanger)
clicker.place(x=600, y=400)
clicker.pack()
clicknumber.pack()


root.mainloop()

Add a global i after def numberchanger():

from tkinter import *

root = Tk()
i = 0

def numberchanger():
    global i
    i = i + 1
    print(i)
    clicknumber.config(text=i)


clicknumber = Label(text=i, fg="blue", font="Arial 50 bold")
clicknumber.place(x=600, y=200)

clicker = Button(text="click", bg="red", fg="green", font="Arial 20 bold", command=numberchanger)
clicker.place(x=600, y=400)
clicker.pack()
clicknumber.pack()


root.mainloop()
