A small module for fetching and parsing stuff from EFA on the DBWebsite. Also provides command line utility so you can quickly see if your train is on time or not. I wrote this with python 3.3+ in mind but it also runs on 2.7+ on my machine.
After doing pip install seins you can use the command line tool called seins or just s1. The output will look
somewhat like this:
$ s1
------------ Connections from: Universität s-Bahnhof, Dortmund to: Dortmund hbf
departure, arrival, delay, connection
11:19, 11:26, +0, S
11:39, 11:46, +2, S
11:59, 12:06, +3, S
12:19, 12:26, +0, S
Use s1 --help for more information
Just import the module into your project and get a DBPageParser instance.
from seins.PageParser import DBPageParser
page = DBPageParser(departing_station, arrival_station, day=None, departure_time=None)
#returns a list of tuples of the form (departure_time, arrival_time, delay, connection_type)
connections = page.connections
You can specify an optional departure time and day. If not provided the current time and day will be used as defaults
The PageParser can produce some Exceptions depending on your input. Or if there are connection problems to the DB
from seins.PageParser import DBPageParser, PageContentError
from seins.HtmlFetcher import FetcherException
try:
page = DBPageParser(departing_station, arrival_station)
except PageContentError as e:
logger.error('Webpage returned an error message: ' + str(e))
except FetcherException as e:
logger.error('Fetcher could not get valid response from server: ' + str(e))
