How to clear the Entry widget after a button is pressed in Tkinter?

Question

I\'m trying to clear the Entry widget after the user presses a button using Tkinter.

I tried using ent.delete(0, END), but I got an error

Answer 1

real gets the value ent.get() which is just a string. It has no idea where it came from, and no way to affect the widget.

Instead of real.delete(), call .delete() on the entry widget itself:

def res(ent, real, secret):
    if secret == eval(real):
        showinfo(message='that is right!')
    ent.delete(0, END)

def guess():
    ...
    btn = Button(ge, text="Enter", command=lambda: res(ent, ent.get(), secret))
