Изменить программу так, чтобы вы могли вводить в однострочное текстовое поле
общее количество палочек, с которыми вы будете играть. Заменить компьютер на
второго игрока

from tkinter import*

b2.config(state="disabled")
b1.config(state="normal")
if n==1:
k3.config(text="Игрок победил!")
b1.config(state="disabled")
b2.config(state="disabled")

character at index. If two are given, the range from "first" to "last" will be deleted. Use delete(0, END) to delete all text in the widget.

import tkinter as tk

def show_entry_fields():

print("First Name: %s\nLast Name: %s" % (e1.get(), e2.get()))

e1.delete(0, tk.END)

e2.delete(0, tk.END)

master = tk.Tk()

tk.Label(master, text="First Name").grid(row=0)

tk.Label(master, text="Last Name").grid(row=1)

e1 = tk.Entry(master)

e2 = tk.Entry(master)

e1.insert(10, "Miller")

e2.insert(10, "Jill")

e1.grid(row=0, column=1)

e2.grid(row=1, column=1)

tk.Button(master,

text='Quit',

command=master.quit).grid(row=3,

column=0,

sticky=tk.W,

pady=4)

tk.Button(master, text='Show', command=show_entry_fields).grid(row=3,

column=1,

sticky=tk.W,

pady=4)

master.mainloop()

tk.mainloop()

The next example shows, how we can elegantly create lots of Entry field in a more Pythonic way. We use a Python list to hold the Entry descriptions, which we include as labels into the application.

import tkinter as tk

fields = 'Last Name', 'First Name', 'Job', 'Country'

def fetch(entries):

for entry in entries:

field = entry[0]

text = entry[1].get()

print('%s: "%s"' % (field, text))

def makeform(root, fields):

entries = []

for field in fields:

row = tk.Frame(root)

lab = tk.Label(row, width=15, text=field, anchor='w')

ent = tk.Entry(row)

row.pack(side=tk.TOP, fill=tk.X, padx=5, pady=5)

lab.pack(side=tk.LEFT)

ent.pack(side=tk.RIGHT, expand=tk.YES, fill=tk.X)

entries.append((field, ent))

return entries

if __name__ == '__main__':

root = tk.Tk()

ents = makeform(root, fields)

root.bind('<Return>', (lambda event, e=ents: fetch(e)))

b1 = tk.Button(root, text='Show',

command=(lambda e=ents: fetch(e)))

b1.pack(side=tk.LEFT, padx=5, pady=5)

b2 = tk.Button(root, text='Quit', command=root.quit)

b2.pack(side=tk.LEFT, padx=5, pady=5)

root.mainloop()

If you start this Python script, it will look like this:
