Make a calendar view for events in python tkinter

Question

So what I'm trying to do is to make a calendar frame, just like the view of google calendar or any other calendar program really, where I can select a day and see the events I have to do on that day and it's time using python tkinter. Currently on my database I have events with date, starting time and ending time. Note that I am using python 3. Can anyone please give me a clue for how to do it or even send a link to a website where it says how to do it. But please, I'm not searching for a date picker just a calendar showing me what thing I should do when. Thank you ;)

Either learn tkinter and you will know how to do it, or learn some HTML and CSS and use a Python web framework (such as flask or django, or many others) to build it the web way. There are entire books on both paths, but also documentation in the web. — progmatico, Dec 23 '17 at 19:05
`tkinter` has `grid()` layout which you can use with `Label`s or `Button`s to create calendar view. — furas, Dec 23 '17 at 19:18
btw: Python has module [calendar](https://docs.python.org/3.6/library/calendar.html) to genearet calendar in text or HTML but it can also be used to build other generator - `import calendar ; text = calendar.TextCalendar() ; print(text.formatmonth(2017, 12)) ; print(text.formatyear(2017))` — furas, Dec 23 '17 at 19:26

EDIT: I found on SO: How do I create a date picker in tkinter?.

There are widgets for tkinter which use calendar too

(but if you just need to display events as list then you can need only Label/Button with pack() or Listbox. And this you can find in any tutorial.)

Python has module calendar which can generate calendar as text or HTML

import calendar

text = calendar.TextCalendar() 

print(text.formatmonth(2017, 12))

result:

   December 2017
Mo Tu We Th Fr Sa Su
             1  2  3
 4  5  6  7  8  9 10
11 12 13 14 15 16 17
18 19 20 21 22 23 24
25 26 27 28 29 30 31

Or for full year

print(text.formatyear(2017))

result:

                                  2017

30 31

It can also gives datetime objects for selected month

print(text.monthdatescalendar(2017, 12))

Result

[[datetime.date(2017, 11, 27), datetime.date(2017, 11, 28), datetime.date(2017, 11, 29), datetime.date(2017, 11, 30), datetime.date(2017, 12, 1), datetime.date(2017, 12, 2), datetime.date(2017, 12, 3)],
 [datetime.date(2017, 12, 4), datetime.date(2017, 12, 5), datetime.date(2017, 12, 6), datetime.date(2017, 12, 7), datetime.date(2017, 12, 8), datetime.date(2017, 12, 9), datetime.date(2017, 12, 10)], 
 [datetime.date(2017, 12, 11), datetime.date(2017, 12, 12), datetime.date(2017, 12, 13), datetime.date(2017, 12, 14), datetime.date(2017, 12, 15), datetime.date(2017, 12, 16), datetime.date(2017, 12, 17)], 
 [datetime.date(2017, 12, 18), datetime.date(2017, 12, 19), datetime.date(2017, 12, 20), datetime.date(2017, 12, 21), datetime.date(2017, 12, 22), datetime.date(2017, 12, 23), datetime.date(2017, 12, 24)], 
 [datetime.date(2017, 12, 25), datetime.date(2017, 12, 26), datetime.date(2017, 12, 27), datetime.date(2017, 12, 28), datetime.date(2017, 12, 29), datetime.date(2017, 12, 30), datetime.date(2017, 12, 31)]]

And you can use Calendar to create class which generates tkinter.Frame like this:

# --- class ---

import calendar
import tkinter

class TkinterCalendar(calendar.Calendar):

    def formatmonth(self, master, year, month):

        dates = self.monthdatescalendar(year, month)

        frame = tkinter.Frame(master)

        self.labels = []

        for r, week in enumerate(dates):
            labels_row = []
            for c, date in enumerate(week):
                label = tkinter.Button(frame, text=date.strftime('%Y\n%m\n%d'))
                label.grid(row=r, column=c)

                if date.month != month:
                    label['bg'] = '#aaa'

                if c == 6:
                    label['fg'] = 'red'

                labels_row.append(label)
            self.labels.append(labels_row)

        return frame


# --- example how to use ---

import tkinter as tk

root = tk.Tk()

tkcalendar = TkinterCalendar()

for year, month in [(2017, 11), (2017, 12), (2018,1)]:
    tk.Label(root, text = '{} / {}'.format(year, month)).pack()

    frame = tkcalendar.formatmonth(root, year, month)
    frame.pack()

root.mainloop()

It still need to display events in calendar and assign function to buttons (every date is tkinter.Button).
