The Python practical sessions are written in Jupyter notebooks.
They are available to you on the astronomy group Python server, and the idea is that you complete the version found there and submit it for grading.
To start this practical on the astronomy group Python server, follow the instructions here, using the assignment name “Session3”.
If you want to work instead on a local copy, a zip file of all the homeworks, and the associated data can be downloaded here.
If you work on a local copy, upload your completed homework to the astronomy group Python server. You can do this using the “upload” button in the Jupyter notebook. The completed notebook must be in a folder in your home directory named “Session3”. You can then submit as normal following the instructions.
