Brian #1: Scipy lecture notes
- “One document to learn numerics, science, and data with Python”
- Topics
- Python language tutorial
- NumPy, Matplotlib, scipy
- Debugging, optimizing, image manipulation
- Statistics, scikit-image, scikit learn
- 3D plotting
- Nice table of contents layout that makes it easy to jump right to whatever you need to learn.
- Just in time learning for scientific Python.
Michael #2: Building a desktop notification tool for Linux using python
- The term desktop notifications refer to a graphical control element that communicates certain events to the user without forcing them to react to this notification immediately.
- Example: we are going to build a notification tool which displays the current rate of bitcoins in INR.
- Based on notify2 package
Brian #3*:* pytest-benchmark
- Easily wrap some time constraints around some code to make sure certain parts of your system don’t slow down.
- Good table or graph based preliminary times with statistics
- Can generate golden sets of numbers, then compare against those and fail based on changes in particular stats like min, mean, etc.
- Can have max and min times for benchmarks even without previous training.
- Lots of fun flags and utilities.
- good integration with pytest
Michael #4: Alice in Python projectland
- via Vicki Boykis
- Python project structure and packaging standardization is still not a solved problem
- In the JVM, as long as you have your path structured correctly, build tools will understand it and create a package for you into an executable JAR.
- But, when I started looking for the same standardization in Python, it wasn’t as straightforward. Some questions I had as I worked:
- Should I be using virtualenvs?
- Pipenvs?
- Setuptools?
- Should I have a setup.cfg?
- What are wheels, or eggs, for that matter?
- Does each folder need an __init__.py?
- What does that file even do?
- How do I reference modules along the same PYTHONPATH?
- Hat tip to pipreqs
- Conclusion: Python project structure and packaging can be intimidating, but, if you take it step by step, it doesn’t have to be.
Brian #5: How to teach technical concepts with cartoons
- Just draw more pictures.
- You don’t have to be a good artist for drawings to help with retention when you are trying to teach technical concepts.
Michael #6: Halo: Beautiful terminal spinners in Python
- We’ve talk about progressbars: tqdm: https://github.com/tqdm/tqdm
- doesn’t have to be.
- Cool methods like
spinner.start([text])spinner.succeed([text])spinner.fail([text])- Windows File Progress Dialog Author: https://xkcd.com/612/
