Google calendar API free slots - api

Question

i am really new to the coding and would like to ask for some advice regarding calendar API.
I managed to created a list of the events and and show a busy time in the calendar, but i cant figure out how to show output of the free slots between the events.
# 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='<email>', 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'])"""
cst = timezone('UTC')
the_datetime_start = cst.localize(datetime.datetime(2020, 6, 10, 0))
print(the_datetime_start)
the_datetime_end = cst.localize(datetime.datetime(2020, 6, 10, 16))
print(the_datetime_end)
body = {
"timeMin": the_datetime_start.isoformat(),
"timeMax": the_datetime_end.isoformat(),
"timeZone": 'UK',
"items": [{"id": '<email>'}]
}
eventsResult = service.freebusy().query(body=body).execute()
print(eventsResult)

Hard to give you a code answer with your information, but if you want to show your free slots, you just have to:
Get all the tasks you have on your planning
Order it
Compare the first end date/hour task with the second start date/hour task
The différence between is your free slot, so you have your free slot
Do it again for the second task and the third task, and repeat for the other task
