I wanted to run this program posted here http://tkinter.unpythonic.net/wiki/TkTableCalendar, but to run this I need the
File "tktable.py", line 115, in __init__
master.tk.call('package', 'require', 'Tktable')
_tkinter.TclError: can't find package Tktable
After searching for a long time I found this
which solves my problem.
TkTableCalender.py is running properly.
