I need a python GUI script.

Hints: you can use the function monthrange from calendar module to get the start weekday and total number of days for a particular month.

This dialog gives you an entry field to enter an appointment. When you click button OK, the dialog window will disappear. However, when you click the same day button in the main calendar window again, the dialog window should reappear together with the appointment information.

You may use the askstring function from module tkinter.simpledialog for the dialog window. It takes the window title and label as input and returns whatever the user typed. For example, the last dialog window was created with the function call

askstring('example', 'Enter text')

When the user clicks OK, the string typed in the entry box is returned by this function call. The function can also take an optional argument initial value that takes a string and puts it in the entry field:

askstring('example', ' Enter text', initialvalue='appt with John')

Thanks for your time!!
