query Good for method chaining, i.e. adding more methods or filters without assigning a new variable. masking general purpose, this is probably the most common method you see in training/examples isin capable of including multiple strings to include contains Good For partial matches MASKS anything that we put inside of square brackets can be set as a variable then passed in. Operators & - and ~ - not | - or AVAILABLE and NAME AVAILABLE or NAME AVAILABLE and not NAME

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 functi…

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.

After taking a look at that post today, I wanted to put a better data science example in here to help folks get started. I use it in more places than I probably should Before we get into it, I want to make a shout out to Kenneth Reitz for making this so easy. Kenneth is a python God for all that he has given to the community in so many ways, especially with his ideas in bu…

These cover 90% of my usage. If I wanted to change something in the second half I would just paste in this command and edit it.
