生成的单词打印到终端，但不是GUI输入-Tkinter

Question

目的是从列表中随机提取一个单词，并将其显示在GUI的屏幕上。当我点击按钮"时，这些字显示在终端中；dammi"；但我无法将它们显示在GUI中。我尝试过Entry和Label，但都没有成功。

from tkinter import *
import random
# Window
root = Tk()
root.geometry("400x350")
root.title("Passato Remoto")
root.configure(bg="#000000")
root.resizable(False, False)
# Find Verb
verbi = ['Dare', 'Dire', 'Fare', 'Sapere', 'Prendere']
# Dammi Button
def give():
print(random.choice(verbi))
# Create Buttons
dammi = Button(root, text='Dammi un verbo',
bg='#ffffff',
fg='#000000',
borderwidth=0,
highlightthickness=0,
font=('Helvetica', 16),
height=2,
width=10,
command=give)
dammi.grid(column=0, row=2, pady=50, padx=25)
con = Button(root, text='Coniugazione',
bg='#ffffff',
fg='#000000',
borderwidth=0,
highlightthickness=0,
font=('Helvetica', 16),
height=2,
width=10)
con.grid(column=2, row=2, pady=50, padx=25)
# Put Verb On Screen
verb = Entry(root, text=give(), font=('Helvetica', 40), width=10, bg="#ffffff", fg="#000000")
verb.grid(column=0, columnspan=3, row=1, pady=50, padx=80)
root.mainloop()

最简单的方法可能是使用StringVar。我已将此添加到问题代码中。

from tkinter import *
import random
root = Tk()
root.geometry("400x350")
root.title("Passato Remoto")
root.configure(bg="#000000")
root.resizable(False, False)

# Find Verb

verbi = ['Dare', 'Dire', 'Fare', 'Sapere', 'Prendere']

# Dammi Button

sample = StringVar()           # Added

def give():                    # Changed
sample.set( random.choice(verbi) )
print( sample.get() )

# Create Buttons

dammi = Button(root, text='Dammi un verbo',
bg='#ffffff',
fg='#000000',
borderwidth=0,
highlightthickness=0,
font=('Helvetica', 16),
height=2,
width=10,
command=give)
dammi.grid(column=0, row=2, pady=50, padx=25)

con = Button(root, text='Coniugazione',
bg='#ffffff',
fg='#000000',
borderwidth=0,
highlightthickness=0,
font=('Helvetica', 16),
height=2,
width=10)
con.grid(column=2, row=2, pady=50, padx=25)

# Put Verb On Screen
#                                          changed here
verb = Label(root, font=('Helvetica', 40), textvariable = sample, width=10, bg="#ffffff", fg="#000000")
verb.grid(column=0, columnspan=3, row=1, pady=50, padx=80)
give()   
root.mainloop()
