Hi please assist me in implementing code for updating the data file of the following code.

def volunteers_input():

next_7_days = []

time = []

for day in range(7):

next_7_days.append(str(datetime.now()+datetime.

timedelta

(days=day))[:10])

for times in range(8):

time.append(str(datetime.now()+datetime.timedelta(

hours

=times))[11:19])

print(next_7_days)

print(time)

while True:

user_input = input("Acceptable format[yyyy-mm-dd]

Input date: "

)

# user_input = input("Acceptable format[hh:mm] Input time: ")

if user_input in next_7_days:

break

return user_input

# volunteers_input()

def check_time():

while True:

user_input = input("Acceptable format[hh:mm]

Input time: "

)

time = user_input.split(':')

hour = int(time[0])

min = int(time[1])

if hour 16 and hour > 8:

if min >= 0 and min 60:

break

return user_input

# check_time()

def create_event(service):

date = volunteers_input()

time = check_time()

event = {

event = service.events().insert(calendarId=

Volunteer for a slot As a student that wants to volunteer their time in the coding clinic, I want to indicate my availability for a specific slot. - Do not allow double booking for volunteers - The booking should also show on the volunteer's personal Google Calendar - The data file for the volunteer should be updated as well
