Python System Tray Python app issue with building a list.

[splaq]

I am working on an app right now that is basically google calendar in your system tray, I'm running into the issue in the build_calendar_list() method. I'll post the code below, but everything works the way I would expect until I choose a calendar from my list of calendars. When I choose a calendar I expect to get back the calendar id of the chosen calendar. But I only ever get back the the id for the last item in the list. That's a very basic idea of the program and the problem.. Here is the code..

from __future__ import print_function

import datetime
import os.path
import pprint
import sys

from google.auth.transport.requests import Request
from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError

from PIL import Image
from pystray import Icon as icon, Menu as menu, MenuItem as item


# If modifying these scopes, delete the file token.json.
SCOPES = ['https://www.googleapis.com/auth/calendar']

class MyCalendar:
    def __init__(self):
        """Shows basic usage of the Google Calendar API.
            Prints the start and name of the next 10 events on the user's calendar.
        """
        self.creds = None
        # The file token.json stores the user's access and refresh tokens, and is
        # created automatically when the authorization flow completes for the first
        # time.
        if os.path.exists('token.json'):
            self.creds = Credentials.from_authorized_user_file('token.json', SCOPES)
        # If there are no (valid) credentials available, let the user log in.
        if not self.creds or not self.creds.valid:
            if self.creds and self.creds.expired and self.creds.refresh_token:
                self.creds.refresh(Request())
            else:
                flow = InstalledAppFlow.from_client_secrets_file(
                    'credentials.json', SCOPES)
                self.creds = flow.run_local_server(port=0)
            # Save the credentials for the next run
            with open('token.json', 'w') as token:
                token.write(self.creds.to_json())

        try:
            # Call the Calendar API
            self.service = build('calendar', 'v3', credentials=self.creds)
            self.cal_id = None
            self.cal_list = self.build_calendar_list()
            print(dir(self.cal_list[0]))


        except HttpError as error:
            print('An error occurred: %s' % error)


    # def get_events(self):
    #     now = datetime.datetime.utcnow().isoformat() + 'Z'  # 'Z' indicates UTC time

    #     events_result = self.service.events().list(calendarId=self.get_cal_id(), timeMin=now,
    #                                         maxResults=10, singleEvents=True,
    #                                         orderBy='startTime').execute()
    #     events = events_result.get('items', [])

    #         start = event['start'].get('dateTime', event['start'].get('date'))

    def set_cal_id(self, cal_id):
        self.cal_id = cal_id
        print(self.cal_id)
        # return self.cal_id
   
    def get_cal_id(self):
        return self.cal_id


    def tray_icon(self):
        image = Image.open("icon.ico")
        return image

    def good_bye(self, icon):

        icon.visible = False
        icon.stop()

    def create_tray(self):

            icon=self.tray_icon(),
            menu=menu(
                item(
                    'Quit',
                    self.good_bye,
                ),

                        lambda: (item for item in menu_items)
                    ),
                ),
            ),

    def build_calendar_list(self):
        '''

        '''
        cal_list = []
        calendarlist = self.service.calendarList().list().execute()

        for k in calendarlist.get('items', tuple()):

            cal_list.append(
                ## ISSUE:
                ## All k['id'] come back as the last item in the list.
                ## IE. All lambda: self.set_cal_id(k['id']) => lambda: self.set_cal_id('addressbook#[email protected]')
                ## 0 understanding as to why.
                (item(k["summary"], lambda *args: self.set_cal_id(k['id'])))
            )
       
        return cal_list


if __name__ == '__main__':
    my_cal = MyCalendar()
    my_cal.create_tray()

I believe what's going on is that for whatever reason the lambda function in my build_calendar_list() method is causing all of my id's to default to the last item in the list of calendars. If that's the case then what can I do to correct that? The idea is to be able to choose a calendar and get a quick view of events for that calendar or add an event etc.
