Get and display event id for Google Calender api (Python)

Question

I am using the basic quickstart program to test code before adding it to my work project, and I am having trouble with how to retrieve the event ids and display them. Once I manage this step, I'm going to store them and use the ids to delete events.

Here is my errror:

event = service.events().get(calendarId='primary', eventId='eventId').execute() File "/Library/Python/2.7/site-packages/googleapiclient/_helpers.py", line 130, in positional_wrapper return wrapped(*args, **kwargs) File "/Library/Python/2.7/site-packages/googleapiclient/http.py", line 856, in execute raise HttpError(resp, content, uri=self.uri) googleapiclient.errors.HttpError: https://www.googleapis.com/calendar/v3/calendars/primary/events/eventId?alt=json returned "Not Found">

The code that's generating it is:

from __future__ import print_function
import datetime
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

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

def main():
    """Shows basic usage of the Google Calendar API.
    Prints the start and name of the next 10 events on the user's calendar.
    """
    creds = None
    # The file token.pickle 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.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(creds, token)

    service = build('calendar', 'v3', credentials=creds)

    # Call the Calendar API
    now = datetime.datetime.utcnow().isoformat() + 'Z' # 'Z' indicates UTC time
    print('Getting the upcoming 10 events')
    events_result = service.events().list(calendarId='primary', timeMin=now,
                                        maxResults=10, singleEvents=True,
                                        orderBy='startTime').execute()
    events = events_result.get('items', [])

    if not events:
        print('No upcoming events found.')
    for event in events:
        start = event['start'].get('dateTime', event['start'].get('date'))
        print(start, event['summary'])
    event = service.events().get(calendarId='primary', eventId='eventId').execute()

    print(event['summary'])

    #service.events().delete(calendarId='primary', eventId='4qvgpuca08lp3rki5vnuo7qp7r').execute()
if __name__ == '__main__':
    main()

I'm still very new, so I am sure it's a foolish mistake. I tried wrapping eventID in the service.events().list section, but no success.

You are using the String eventId where you should have an actual event Id. So you could change your code here from this:

    if not events:
        print('No upcoming events found.')
    for event in events:
        start = event['start'].get('dateTime', event['start'].get('date'))
        print(start, event['summary'])
    event = service.events().get(calendarId='primary', eventId='eventId').execute()

    print(event['summary'])

    #service.events().delete(calendarId='primary', eventId='4qvgpuca08lp3rki5vnuo7qp7r').execute()
if __name__ == '__main__':
    main()

To this:

    if not events:
        print('No upcoming events found.')
    for event in events:
        start = event['start'].get('dateTime', event['start'].get('date'))
        print(start, event['summary'])
        service.events().delete(calendarId='primary', eventId=event['id']).execute()

if __name__ == '__main__':
    main()

This way you are already deleting the events after listing them. Notice the syntax for eventId=event['id']. The id is a property of the Event object. You can see the rest of the properties here.
