ptv-timetable 0.2.0

Python API wrappers to interact with the Public Transport Victoria Timetable API and Yarra Trams TramTracker service

PTV Timetable and TramTracker API wrappers for Python (pre-release)

Modules to interface with the Public Transport Victoria (PTV) Timetable API and Yarra Trams' TramTracker data service in a Python-friendly manner.

Package version: 0.2.0
Last updated: 1 September 2024

Overview

The goal of this package is to provide documented and easy-to-use interfaces (API wrappers) to interact with the PTV Timetable API and TramTracker service in Python, with minimal transformation to the responses from the API. A secondary aim is to minimise the use of modules that are not part of the standard library to increase portability.

What's different from accessing the Timetable API directly?

• Simplifying output "types": instead of having a different response schema for each API operation, any object that represents the same concept are consolidated into the same response type (e.g. all responses that represent a public transport stop are instances of the same class: Stop, instead of the ten or so different representations in the API). Any attribute/field for which the API does not provide a response for will have the value None.
• Best-effort documentation: all operations and fields have, as far as practicable, been documented in type hints and docstrings (although some of these are guesses).
• Date and time representation: date inputs and outputs are converted from and to datetime objects with the local time zone of Victoria, so that you do not have to deal with the different string representations of dates and speaking to the API in the UTC time zone.
• Other quality of life modifications: such as consistent attribute names, fixing typos and removing trailing whitespaces.

tzdata	≥ 2024.1	Only required on OSes without a native tz database, including Windows.

Usage

This package adds two modules into the root namespace of your interpreter (so they can be directly imported into your code with import <module_name>):

• ptv_timetable for interacting with the PTV Timetable API;
  • ptv_timetable.types defines dataclasses used to represent returned API objects; and
• tramtracker for interacting with the TramTracker data service.

Each module defines data types that encapsulate the responses from the APIs so as to allows access by attribute reference (.) to take advantage of autocompletion systems in IDEs where available. This format also allows each field to be documented, which is not a feature that's available in the raw dicts returned by the APIs.

Each module defines a class to interface with the APIs (ptv_timetable.TimetableAPI and tramtracker.TramTrackerService) with methods for each supported operation. ptv_timetable.TimetableAPI needs to be instantiated before use with credentials obtained from PTV from this page. tramtracker.TramTrackerService methods can be used directly without creating an instance as credentials are not required and all methods are defined as class methods.

Logging

Some actions are logged under the logger names ptv-timetable.ptv_timetable and ptv-timetable.tramtracker. Use logging.getLogger() to obtain the loggers and you can register your own handlers to retrieve their contents.
