[英]How do I reassign Label text with Tkinter from a different function
from tkinter import *
# reassigns variables for label and button texts
def Ctrack(vname, vvalue):
#global vname
vname = vvalue
#place holder to check which button has been clicked
print(vname)
#labeltext = reassign label text bas
# creates labels and buttons
def buttons():
root = Tk()
#first label
winlabel = Label(root, text =labeltext )
winlabel.grid(row = 0, column = 1, padx = 10, pady = 10)
#first button
but1 = Button(root, text = "button 1", command = lambda *args: Ctrack(0, 1))
but1.grid(row = 0, column = 2, padx = 10, pady = 10)
#second button
but2 = Button(root, text = "button 2", command = lambda *args: Ctrack(0, 2))
but2.grid(row = 0, column = 3, padx = 10, pady = 10)
root.mainloop()
buttons()

How do I reassign the label text in my buttons function to whatever I assign the variable in the Ctrack function?如何将按钮函数中的标签文本重新分配给我在 Ctrack 函数中分配的变量?
You can give the Ctrack() function the ability to post the Label on the root window.您可以让 Ctrack() 函数能够在根窗口上发布标签。 If you go with that approach, you can add 'root' as an argument in Ctrack() and then declare-and-pack the Label within the Ctrack() function.如果您采用这种方法,您可以在 Ctrack() 中添加“root”作为参数,然后在 Ctrack() 函数中声明并打包标签。
