Здравствуйте,

Установил с Сизифа python22 и tkinter22,

Набрал с книги простой пример (вычисление площади круга), запускаю файл - появляется только пустой серый квадратик с заголовком.
Никаких полей для ввода, кнопок...


в чём может быть ошибка?


текст примера:

******

#!/usr/bin/env python
from Tkinter import *
import math

def Square(radius):
    return math.pi * radius**2


def calculate_square():
  radius = float(radius_entry.get())
  try:
      square = "%11.3f" % Square(radius)
  except:
      square = "?"
  square_label.configure(text=square)

root = Tk()
root.title("Площадь круга")
frame = Frame(root)
radius_entry = Entry(frame, width=10)
radius_entry.grid(row=0, column=0)
square_label = Label(frame, text="?")
square_label.grid(row=0, column=1)
eval_button = Button(frame, text="Вычислить", width=10,
                     command=calculate_square)

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

exit_button = Button(frame, text="Выход", width=10,
                     command=root.destroy)

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

root.mainloop()

******


Или что набрать, чтобы проверить, что ktinter работает нормально?
