Welcome to the Python Data Science Toolbox! My name is Hugo Bowne-Anderson and I'm a Data Scientist at DataCamp. These courses are for those who have taken DataCamp's introductory Python courses and are itching to develop their Python data science skills further. You are already versed in the basics of Python variables and know about ints, floats, strings and booleans, all essential building blocks for budding Pythonistas. You're also familiar with lists and dictionaries, objects which you'll invariably use to store data in your work. You have learnt about functions and packages, how to use numpy to store, access and manipulate numerical data. You know about control flow, pandas DataFrames and how to plot with matplotlib, along with having had a deep dive into hacker statistics.
