[Python] How to create a DD path for a method

Can anyone help me with creating a DD path for a specific method? I tried making one but I am not sure that it is correct.

The method is:

@register.filter(name="book")
def book(travel_date, travel_time):

travel_dt = add(travel_date, travel_time)
travel_ndt = datetime.strptime(travel_dt, '%Y-%m-%d %H:%M:%S')
current_ndt = datetime.now()

delta = travel_ndt - current_ndt
total_hours = int(delta.total_seconds() // 3600)

for hour in range(total_hours + 1):
if hour >= 1:
return True
return False
