Web scraping is a very essential tool for programmers to learn to gather data from websites. Specifically, for Data Scientists web scraping is goto tool to gather data from websites. We can use bs4.BeautifulSoup or selenium in Python to scrape any website.

You can see some of my projects where I scraped websites like 99acres.com, flipkart.com, housing.com and gather useful data for my Data Science projects like arv-anshul/campusx-real-estate.

I have learned Web Scraping from YouTube only.

Tree based models and Regression models are widely used Machine Learning models. So more you know about them is better for you. Also, many concepts from these models are borrowed by advance Machine Learning models like Gradient Boosting, XGBoost, etc.

These models are also great choice for :fontawesome-user-tie: interviewers so from these models they ask many interview questions. This blog mainly focuses on tree based models.
