  • Python 2.7 or Python 3
  • The flask python library to run the web examples

Installation and Examples

From PyPI

pip install fiftyone_devicedetection

You can confirm this is working with the following micro-example.

  • Create a resource key for free with the 51Degrees configurator. This defines the properties you want to access.
  • On the 'implement' page of the configurator, copy the resource key and replace YOUR_RESOURCE_KEY in the example below. Save this as exampledd.py
  • Run the example with python exampledd.py
  • Feel free to try different user-agents and property values.
from fiftyone_devicedetection.devicedetection_pipelinebuilder import DeviceDetectionPipelineBuilder
pipeline = DeviceDetectionPipelineBuilder({"resourceKey": "YOUR_RESOURCE_KEY"}).build()
fd = pipeline.create_flowdata()
fd.evidence.add("header.user-agent", "Mozilla/5.0 (iPhone; CPU iPhone OS 12_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148")

For more in-depth examples, check out the examples page in the documentation.
