Simplified data retrieval from Entur in Python

Pythentur

This package provides functions for simple fetching of real-time public transport data - as provided by Entur. As an added bonus, the nsrGet-function makes it easy to obtain the NSR ID of a stop place by a search string.

Usage

StopPlace object

Create a StopPlace object by handing in the NSR ID to the constructor.

from pythentur import StopPlace
oslo_s = StopPlace("NSR:StopPlace:59872")

This stores the ID, the name of the stop place (if available) and a pre-made query template in the GraphQL format.

The number of calls to retrieve can be changed by changing the argument noDepartures in the get method. The default is 20.

StopPlace.get method

This method makes a request to the Entur GraphQL API, by populating the query template with the NSR ID and the number of calls to get. This retrieves a list of calls, each represented by a dictionary.

from pythentur import StopPlace
oslo_s = StopPlace("NSR:StopPlace:59872")
data = oslo_s.get()

Here, data is a list of dictionaries, each containing:

• 'platform': String containing the platform this call is arriving on. May be a blank string if the stop place does not have different specified platforms.
• 'line': String containing the line number and name of the arriving transport.
• 'aimedArrivalTime': Datetime object containing the planned arrival time of the call.
• 'expectedArrivalTime': Datetime object containing the expected arrival time of the call.
• 'delay': Timedelta object containing the calculated delay of the call.
• 'readableTime': Returns a human readable string with relative time from now to the expected departure.

nsrGet function

Utilizing nsrGet, finding NSR IDs becomes a breeze. Hand in a search string to the function, and it spits out a list of IDs from stop places matching that string.
