#17: Google's Python is on fire and Simon says you have CPU load Pythonically
#1 Brian: python-fire
- Suggested by several listeners
- Under the Google repo set on github but not a Google product.
- “Python Fire is a library for automatically generating command line interfaces (CLIs) from absolutely any Python object.”
Some Benefits as listed on the project page
- a simple way to create a CLI in Python.
- a tool for exploring and debugging Python code.
- exploring existing code by turning other people's code into a CLI.
- makes transitioning between Bash and Python easier.
- Enough documentation right in the github repo for me to try it out.
- Concise but thorough documentation, as well.
- I wouldn’t ship a CLI with this, as it’s too heavy.
- depends on ipython and six
- It would be useful to very quickly throw together a CLI to try out some Python code from bash.
- For internal development and debugging tools.
- I think this week I’m going to try to build a few CLI tools for directly sending and receiving commands to some test instruments.
#2 Michael: Simon: Simple macOS menubar system monitor, written in Python 3.6 + pyobjc
- Shows how simple a menubar app can be
- Nice example of a platform-native Python app (we need more of these)
- Could use it as a starter app for your ideas on macOS
#3 Brian: Free Food A couple of amusing Reddit posts about free food.
#4 Michael: HTTPie
- Pronounced aitch-tee-tee-pie
- A command line HTTP client with an intuitive UI, JSON support, syntax highlighting, wget-like downloads, plugins, and more.
- A picture is worth many words, have a look: https://httpie.org/
- Excellent support for JSON, XML, HTTP response headers, etc
- I spoke before about Postman as an API test client, this is the CLI version.
#5 Brian: pipdeptree
- Sometimes when doing
pip listI see way more packages than I remember installing. That’s due to dependent installs.
pipdeptreeis a simple command line tool that shows you your installed packages in an ascii tree structure so you can see who depends on.
arrow? I don’t remember installing that. Ah.
arrowis a dependency of
jinja2-time,which is a dependency of
cookiecutter, that I do remember installing.
- When we were getting SignifAI off the ground, one of the biggest decisions we had to make right at the beginning was what our stack would be.
- We know Python but…
- But it’s important to note that our product and infrastructure must support hundreds of thousands of events per second.
- So we were happy to see that, with the recent widespread adoption of Python 3 and the introduction of tasks and coroutines as first-class citizens in the language, Python has recently stepped up its game.
- Python 3 has continued evolving into a new wave of libraries that disrupt and change old assumptions about Python performance for web applications.
- Python’s GIL, is it a true roadblock?
- UVLoop is the first ultra-fast asynchronous framework, which is a drop-in replacement for Python 3.5’s built-in asyncio event loop. Both Japronto and Sanic which are reviewed in this post are also based on UVLoop.
- The future of Python is here: Overall, it looks like fast, asynchronous Python might be here to stay. Now that asyncio appears to be a default in Python and the async/await syntax has found favor among developers, the GIL doesn’t seem like such a roadblock anymore and speed doesn’t need to be a sacrifice.

- Sasha Cuerda’s tweet: https://twitter.com/sashacuerda/status/839839014836453377 @mkennedy @brianokken Just used the aiohttp example you talked about to refactor a CLI scraper...went from > 8' to < 45". Blown away.
