Here is one take on it:-
import calendar, Tkinter
class TkCalendar(Tkinter.Frame):
def __init__(self, parent, year=2002, month=5):
Tkinter.Frame.__init__(self, parent)
data=calendar.monthcalendar(year, month)
col=0
for day in calendar.day_abbr:
Tkinter.Label(self, text=day).grid(row=0, col=col, sticky='nsew')
col+=1
row=1
for data_row in data:
col=0
for day in data_row:
if day==0:
col+=1
continue
b=Tkinter.Button(self, text=day, command=lambda self=self,
day=day: self.close(day))
b.grid(row=row, col=col, sticky='nsew')
col+=1
row+=1
self.pack()
def close(self, day):
print day
self.quit()
if __name__=='__main__':
root=Tkinter.Tk()
cal=TkCalendar(root)
root.mainloop()
