Over the course of my data science learning, I have had a ton of exposure to Scikit-learn. Scikit learn is one of the most popular machine learning libraries for Python. In this post, I will discuss some important practices to keep in mind when using the Scikit-learn library for building effective models.

In this post, I will demonstrate how to scrape data from tables on Natural Stat Trick, a website for getting standard and advanced NHL statistics. Natural Stat Trick is a reputable and frequently referenced data source for NHL analytics used by writers and fans alike.

First, using the Beautiful Soup library, I’ll go through the steps to scrape the html and convert the data to a Pandas DataFrame. Then, I’ll show a convenient one liner that works for tables on Natural Stat Trick and will work for tables on other webpages depending on their complexity. …
