Python for Data Science and Machine Learning

Course Description
Python is a general-purpose programming language that is becoming more and more popular for doing data
science. Companies worldwide are using Python to harvest insights from their data and get a competitive
edge. Unlike any other Python tutorial, this course focuses on Python specifically for data science. In our
Intro to Python class, you will learn about powerful ways to store and manipulate data as well as cool data
science tools to start your own analyses
 
Data Science and Machine Learning
This course will enable you to gain the skills and knowledge that you need to successfully carry-out real-
world data science and machine learning projects.
 The first part of the course covers data analysis and visualization. You will be working on real datasets
using Python’s Numpy, Pandas, Matplotlib and Seaborn libraries.
 
The second part of the course focuses on machine learning. We will be covering both supervised and
unsupervised learning. We will be working on case studies from a wide range of verticals including finance,
heath-care, real estate, sales, and marketing. Some of the algorithms that will be discussed include Linear
Regression, Logistic Regression,. This course is the foundation for Deep Learning courses in this
specialization.
