Changing the text on a label
self.labelText = 'change the value'The above sentence makes labelText change the value, but not change depositLabel's text.
To change depositLabel's text, use one of following setences:
self.depositLabel['text'] = 'change the value'OR
self.depositLabel.config(text='change the value')
You can also define a textvariable when creating the Label, and change the textvariable to update the text in the label.Here's an example:
labelText = StringVar()depositLabel = Label(self, textvariable=labelText)depositLabel.grid()def updateDepositLabel(txt) # you may have to use *args in some cases labelText.set(txt)There's no need to update the text in depositLabel manually. Tk does that for you.
Use the config method to change the value of the label:
top = Tk()l = Label(top)l.pack()l.config(text = "Hello World", width = "50")
