Data Acquisition and Manipulation with Python [Video]

By: Curtis Miller

Overview of this book

Python, a multi-paradigm programming language, has become the language of choice for data scientists for data analysis, visualization, and machine learning. In this course, you’ll start by learning how to acquire data from the web in its already “clean” format, such as in a .csv file, or a database. You’ll then learn to transform this data so it’s in its most useful format for analysis. After that, you’ll dive into data aggregation and grouping, where you’ll learn to group similar data for easier analysis purposes. From there, you’ll be shown different methods of web scraping using Python. Finally, you’ll learn to extract large amounts of data using BeautifulSoup, as well as work with Selenium and Scrapy.

Grouping Basics
In this video, we will show how we can form and use groups. We will use the DataFrame method groupby() to create groups, then will do the group operations you want. - Identify which columns in the dataset identify groups - Use groupby() to form a group object - Use the group object for GroupWise operations
