Python 3: Web Scraping and Machine Learning
During this hands-on course, participants will work with Python and several popular packages to create programs that acquire, consolidate, analyze and present large data sets. Whether originated from websites or internal databases, this course will demonstrate core techniques to efficiently manage and explore business data.
A general understanding of programming principles and Python is recommended for this course. The course material will build on the content of “Python 1: Core Data Analysis” and “Python 2: Visualization and Analysis”. Participants should be familiar with Python packages and their installation. Participants are expected to download & install Anaconda or an equivalent Python distribution in advance of the course.
