python - set the text of an entry using a button tkinter -

-

i trying set text of entry using button in gui using tkinter. gui me classify thousands of words. 5 categories, each of categories has button. hoping using button speed me , want double check words every time otherwise use button , have gui process current word , bring next word. command buttons reason not behaving want them to. example

def cwin():   win = tk()  v=stringvar()  def settext(word):      v.set(word)   = button(win, text="plant", command=settext("plant") a.pack() b = button(win, text="animal",command=settext("animal")) b.pack() c = entry(win, textvariable=v) c.pack() win.mainloop()

so far when able compile click nothing.

you might want use insert method.

this script inserts text entry. inserted text can changed in command parameter of button.

from tkinter import *  def set_text(text):     e.delete(0,end)     e.insert(0,text)     return  win = tk()  e = entry(win,width=10) e.pack()  b1 = button(win,text="animal",command=lambda:set_text("animal")) b1.pack()  b2 = button(win,text="plant",command=lambda:set_text("plant")) b2.pack()  win.mainloop()
