import csv

class traffic:
def __init__(self, trip_id, operating_date, journey_gid, stop_times_trip_id=None, stop_times_arrival_time=None):
self.trip_id = trip_id
self.date=operating_date
self.journey_gid = journey_gid

self.arrival_time = stop_times_arrival_time

def main():
all_objects = []


with open('todays_trips.csv', 'r') as f:
reader = csv.reader(f)
print(reader)
for each in reader:
print(each)
trip_id = each[0]
operating_date = each[1]
journey_gid = each[2]
data = traffic(trip_id=trip_id, operating_date=operating_date, journey_gid=journey_gid)
all_objects.append(data)
print(each)
