This is the premiere of #PythonLiveLessons, a weekly live stream about Python code and more, hosted by Sebastiaan Mathôt. In this first episode, we'll see how to get started with a new Python project from scratch. And we'll lay out a roadmap for a full development workflow, which we'll walk through in future episodes.

![Set comprehensions in Python [Python comprehensions #3]
[https://www.buymeacoffee.com/cogsci] In this video, I demonstrate set comprehensions in Python. This is a way to build set objects with a single expression. The notebook for this video is available at https://osf.io/2b8wz/. For more tutorials, visit https://python.cogsci.nl/.

![Classifying images with MobileNetV2 using Keras and Python [Part 3]
(See https://python.cogsci.nl for code and written tutorials.) This is the third of a series of video tutorials about deep learning with Keras in Python. Here I show how to import a pretrained neural network, MobileNetV2, and how to use this to classify an image.

![Python Generators 2: send and yield
[https://www.buymeacoffee.com/cogsci] For more Python tutorials, visit http://python.cogsci.nl/. In this video, I demonstrate how you can send information to generator functions to implement bi-directional communication. Code is available on osf.io/eyxc3.
