Update Label Text in Python TkInter

Question

Is there any possible way to create a TkInter label that uses a string and a variable as the text?

For example:

name = \"bob\"
Label(root, text=\"hel         


        

Answer 1

You must tell the label to change in some way.

Here you have an example. The text of the label is a textvariable text defined as a StringVar which can be changed whenever you want with text.set().
In the example, when you click the checkbox, a command change tells the label to change to a new value (here simplified to take two values, old and new)

from Tkinter import Tk, Checkbutton, Label
from Tkinter import StringVar, IntVar

root = Tk()

text = StringVar()
text.set('old')
status = IntVar()

def change():
    if status.get() == 1:   # if clicked
        text.set('new')
    else:
        text.set('old')


cb = Checkbutton(root, variable=status, command=change)
lb = Label(root, textvariable=text)
cb.pack()
lb.pack()

root.mainloop()
