Parikstra

parikstra is a Python module to calculate journey with the Parisian transport system, and read some other interesting data.

It uses official API of Parisian transport websites, but is still an unofficial API client.

It is at the moment in developpement. Use at your own risk.

By the way, parikstra = Paris + Djikstra

Usage

Install parikstra, either cloning this repository

git clone git://github.com/Gawen/parikstra.git

or using pip (or other)

pip install parikstra

Import the parikstra module

import parikstra

Get your departure point

departure = parikstra.Point("nation")

Get your arrival point

arrival = parikstra.Point("dammartin juilly saint mard")

Ask to calculate the itineraries

itineraries = departure.to(arrival)

Print the itineraries' type

for i, itinerary in enumerate(itineraries):
    print "#%d. %s (duration %s)" % (i, itinerary.type, itinerary.duration, )

Let's say you take the first one

itinerary = itineraries[0]

Request the itinerary's steps ...

Iterate the different steps of the journey

for i, step in enumerate(itinerary):
    print "#%d. %s => %s @ %s" % (i + 1, step.name, step.direction, step.time, )

Here you go.

CLI

You can use parikstra as a CLI client.

Usage: parikstra.py [options]

Options:
  -h, --help            show this help message and exit
  -d DEPARTURE, --departure=DEPARTURE
                        Departure
  -a ARRIVAL, --arrival=ARRIVAL
                        Arrival
  -v, --verbose         Verbosify

Example:

$ python parikstra.py --departure "nation" --arrival "aeroport charles de gaule"
