A Whirlwind Tour of Python by Jake VanderPlas

A Whirlwind Tour of Python is a fast-paced introduction to essential features of the Python language, aimed at researchers and developers who are already familiar with programming in another language. The material is particularly designed for those who wish to use Python for data science and/or scientific programming, and in this capacity serves as an introduction to my longer book, The Python Data Science Handbook. The content is also available on Github in the form of Jupyter Notebooks, or from O'Reilly site as a free e-book or free pdf.
