# Python client

# Logging in

For participants interested in trying thing out, try logging into Terrascope openEO backend:

https://docs.terrascope.be/#/Developers/WebServices/OpenEO/OpenEO (opens new window)

Jupyter notebooks with the openEO Python client installed: https://notebooks.terrascope.be (opens new window)

This jupyter environment also has the notebook samples in this git repository already available:

https://github.com/VITObelgium/notebook-samples (opens new window)

Otherwise, git can be used to check out the notebooks, or simply download the 'ipynb' file.

Use 'edugain and social accounts' login to avoid having to register at Terrascope, you may still be required to fill in a form.
