I am lucky enough to be back at PyCon UK again this year, https://2018.pyconuk.org/. Lots of talks, workshops and there are sprints to follow. One of the most inclusive and friendly technical conferences I have ever attended, I am glad to be back again this year. I will be adding write ups for the sessions I attend here: https://asset.blogs.bris.ac.uk/tag/pyconuk2018/
Yay. I have made it to PyCon UK again this year.
I’m starting on day 2 this year but still glad to be here.
As usual the friendly Python community are making everyone feel welcome.
I shall be posting notes and tips I pick up over the next few days.
Visit the conference site for more information about PyConUK.
Look out for the video uploads of the talks post conference too.
