Import Python: Import Python Weekly Issue 111 – Sublime3 and vim for setup, Think Python 2nd ed free

Programing, Python, by admin.

I decided to revisit my editor configuration the other night, and experimented with every possible editor I could think of / imagine. I heavily configured vim (neovim), PyCharm, Eclipse, Emacs (Spacemacs), VSCode, Atom, Textual, and more. I knew I was going to stay put with my choice of Sublime Text 3 (which I have been using for 5+ years), but it’s nice to have validation.

Apart from being a data scientist, I also spend a lot of time on my bike. It is therefore no surprise that I am a huge fan of all kinds of wearable devices. Lots of the times though, I get quite frustrated with the data processing and data visualization software that major providers of wearable devices offer. That’s why I have been trying to take things to my own hands. Recently I have started to play around with plotting my bike route from Python using Google Maps API. My novice’s guide to all this follows in the post.

I love vim and often use it to write Python code. Here are some useful plugins and tools for building a delightful vim python environment, escpecially for Vim8.

User-defined functions (UDFs) are a key feature of most SQL environments to extend the system’s built-in functionality. UDFs allow developers to enable new functions in higher level languages such as SQL by abstracting their lower level language implementations. Apache Spark is no exception, and offers a wide range of options for integrating UDFs with Spark SQL workflows.

Many machine learning algorithms can support categorical values without further manipulation but there are many more algorithms that do not. Therefore, the analyst is faced with the challenge of figuring out how to turn these text attributes into numerical values for further processing.

Seaborn is a wrapper around Matplotlib that makes creating common statistical plots easy. The list of supported plots includes univariate and bivariate distribution plots, regression plots, and a number of methods for plotting categorical variables. The full list of plots Seaborn provides is in their API reference.

Today I am going to demonstrate a simple implementation of nlp and doc2vec. The idea is to train doc2vec model from text document. I had about 20 text files to start with. Although the 20 document corpus seems small but the perk is it takes around 2 minutes to train the model.
