A python client library to query the Targomo API

Project description

targomo_python - Python client library for Targomo webservices


Get your API key here .


the targomo_python library uses python3

make sure this is installed on your system

use virtualenv for a clean, global-free install

virtualenv is great. We can use it to sandbox versions and keep installs contained, so we can avoid global version conflicts.

Install virtualenv

pip install virtualenv

Create python3 virtualenv named 'venv'

virtualenv -p python3 venv

Activate virtualenv

source venv/bin/activate

do this every time to enter into virtualenv called '(venv)' <= as shown in terminal prompt

Install targomo_python

pip install targomo_python

this installs targomo_python and dependencies in our virtualenv

Test the install python -m targomo_python.cli -h this shows the cli usage and help

When you are done using the virtualenv, shut it down


prompt drops '(venv)' tag, virtualenv is no longer active

Library Usage

Example how to use the library from Python code:

#!/usr/bin/env python3
from import ServiceExecutor
from targomo_python.util.TravelOptions import TravelOptions
from targomo_python.util.enum.TravelType import TravelType

travelOptions = TravelOptions()
travelOptions.setTravelTime(10 * 3600)
travelOptions.setFrameDuration(3 * 3600)
travelOptions.addSource({"id": "source-1", "lng": 53.5532, "lat": 10.00644})
travelOptions.addTarget({"id": "target-1", "lng": 53.63265, "lat": 10.00667})

response = ServiceExecutor().execute_service(travelOptions, "route")


Using unit test and nose, API assumes Python 3.x

  • rename tests/ to tests/, add appropriate API key
  • run nosetests -v
