I love digital ocean for it’s simplicity and its commitment to open source.

tqdm is one of my favorite general purpose utility libraries in python. It allows me to see progress of multipart processes as they happen. I really like this for when I am developing something that takes some amount of time and I am unsure of performance. It allows me to be patient when the process is going well and will finish in sufficient time, and allows me to 💥 kill it and find a way to make it perform better if it will not finish in sufficient time. @waylonwalker Add a simple Progress bar! convenience TQDM also has a convenience function called trange that wraps the range function with a tqdm progress bar automatically. notebook support There is also notebook support. If you are bouncing between ipython and jupyter I recomend importing from the auto module. Autoreload in Ipython If you are using notebooks you should enable ipython autoreload 👆

If you are a regular listener of TalkPython or PythonBytes you have hear Michael Kennedy talk about Named Tuples many times, but what are they and how do they fit into my data science workflow. Example # As you graduate your scripts into modules and libraries you might start to notice that you need to pass a lot of data around to all of the functions that you have created. For example if you are running some analysis utilizing,, and data. You may need to calculate total revenue, inventory on hand. You may need to pass these data sets into various models to drive production or pricing based on predicted volumes. Load data # Here we setup functions that can load data from the sales database. Assume that we also have similar functions to and. Create Metrics # Here we create our first function to calculate some metrics. There are likely many of these functions that repeat a similar pattern. They use similar data and have their own custom logic for calculations and joins. Furthermore these…

This post is intended as an extension/update from background tasks in python. I started using the week that Kenneth Reitz released it. It takes away so much boilerplate from running background tasks that I use it in more places than I probably should. After taking a look at that post today, I wanted to put a better data science example in here to help folks get started. This post is intended as an extension/update from background tasks in python.

I have used for several years now with great success and 🔥 rapid reloads. It allows me to move super fast when developing libraries and modules. They have made some great updates this year that allows class modules to be automatically be updated. What I like about autoreload # 🔥 Blazing Fast 💥 Keeps me in the comfort of my text editor 👏 Allows me to use Jupyter when I need 👟 Extremely Reliable One of the biggest benefits that I find is that it shortens the distance between my module/library code and test code inside of a terminal/notebook. Now I primarily use jupyter notebooks for the presentation aspect. I develop code from the comfort of my editor with all of the tools I have setup, and run the functions in a notebook to get the output. From there I might do some aggregations or plots, but the 🥩 meat of development is done outside of jupyter. Now I primarily use jupyter notebooks for the presentation aspect. Enabling Autoreload # 📐 config This is a short script that I use to setup ip…

Throw that mouse Away its time to setup some keyboard shortcuts. These sortcuts were the baseline for switching from tmux/vim to vscode. Most folks posts I was able to find gave great tips on replacing vim, but very few have focused on the hackability of tmux. tmux allows me to rapidly fire up a workspace, create new windows and splits. Then When I switch tasks I can leave that workspace open and and jump right back in later exactly where I left off. There is nothing quite like it. The shortcuts listed here make the transition a bit better. The worst thing I found when using vscode at first was no way to switch between the terminal and editor without the mouse. This first set of keybindings solve that issue.
