London Python Meetup January 2019 – Async Python and GeoPandas

It was a pleasure to go to the London Python Meetup organised by @python_london. There were plenty of friendly people and interesting conversations.

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!

Godot: Dragging and dropping physics objects video

Series: 2D Shapes, drag and drop, new objects

Continuing to explore the Godot 3 game engine. I want to make a game where you drag blocks around and balance them on each other, but I couldn’t find much documentation on how to drag-and-drop objects (except menu UI elements), and especially I found quite a few wrinkles when doing this with objects that are normally controlled by the physics engine.

This time we actually write some code in Godot’s programming language, GDScript.

Godot version: v3.0.6.stable.official.8314054
