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

def create$\_$event$()$:

service $=$ get$\_$calendar$\_$service$()$

title $=$ input$("$Add a title: $")$

location $=$ input$("$Add rooms or location: $")$

description $=$ input$("$Add description: $")$

timezone $=$ input$("$Your timezone $($e$.$g$.,$ Africa$/$Johannesburg$)$: $")$

# Convert date and time inputs to datetime objects

date$\_$input $=$ input$("$Enter the date of the event $($YYYY$-$MM$-$DD$)$: $")$

start$\_$time$\_$input $=$ get$\_$valid$\_$time$\_$input$("$Enter the start time of the event $($HH:MM$)$: $")$

end$\_$time$\_$input $=$ get$\_$valid$\_$time$\_$input$("$Enter the end time of the event $($HH:MM$)$: $")$

start$\_$datetime $=$ datetime.strptime$($date$\_$input $+""+$ start$\_$time$\_$input.strftime$("\%$H:$\%$M$"),"\%$Y$-\%$m$-\%$d $\%$H:$\%$M$")$

end$\_$datetime $=$ datetime.strptime$($date$\_$input $+""+$ end$\_$time$\_$input.strftime$("\%$H:$\%$M$"),"\%$Y$-\%$m$-\%$d $\%$H:$\%$M$")$

# Check for double booking

if check$\_$double$\_$booking$($start$\_$datetime, end$\_$datetime$)$:

print$("$Double booking detected, creating the event in a different time slot."$)$

new$\_$start$\_$time $=$ start$\_$datetime $+$ timedelta$($hours$=1)$ # Move the event by $1$ hour

new$\_$end$\_$time $=$ new$\_$start$\_$time $+$ timedelta$($minutes$=30)$ # Event duration is $30$ minutes

else:

print$("$No double booking detected, creating the event in the specified time slot."$)$

new$\_$start$\_$time $=$ start$\_$datetime

new$\_$end$\_$time $=$ end$\_$datetime
