I gave a talk “Making 100 million requests with Python aiohttp” (slides, Blog post) explaining the basics of writing async code in Python 3 and how I used that to make a very large number of HTTP requests.

Hopefully it was helpful – there were several good questions, so I am optimistic that people were engaged with it.
After that, there was an excellent talk by Gareth Lloyd called “GeoPandas, the geospatial extension for Pandas” in which he explained how to use the very well-developed geo-spatial data tools available in the Python ecosphere to transform, combine, plot and analyse data which includes location information. I was really impressed with how easy the libraries looked to use, and also with the cool Jupyter notebook Gareth used to explain the ideas using live demos.
London Python Meetups seem like a cool place to meet Pythonistas of all levels of experience in a nice, low-pressure environment!
