user interface - python GUI button manipulates label text -

hej,

i want program gui in python compares prompted word (from list) entry. shall possible several times, want make button erases both entry , label , prompts next word list. thus, clicking button shall manipulate text displayed on label. bus how do this?

my code excerpt is:

from tkinter import * = 0   vocablist = ['one', 'two', 'three'] np.random.shuffle(vocablist) vocab = vocablist[i] (...)  class simpleapp_tk(tkinter.tk):     def __init__(self,parent):         tkinter.tk.__init__(self,parent)         self.parent = parent         self.initialize()      (...)          self.label = tkinter.label(self, text=vocab,anchor="w")          self.label.grid(column=1,row=0)      def clear_text():         global                         self.entry.delete(0, 'end')         += 1 # don't know if works!         self.label.insert(0, vocab) # not work!      button_next = tkinter.button(self,text=u"next", command=clear_text)     button_next.grid(column=1,row=1)  if __name__ == "__main__":     app = simpleapp_tk(none)     app.title('rehearse vocabulary: translate!')     app.mainloop() 

i tried

self.label.config(text=vocab) 

instead of .insert-function.

i wondering if problem command or if not work update counter , automatically update variable "vocab" next element list?

thanks help!

try using widget['attribute'] = 'value'. following:

def action(event=none): # event in case bind keypress     entry.delete('0', end) # clear entry     label['text'] = "" # set label's widget text ""     next_word() 

where entry entry widget, label label , next_word() prompts next word.
