Deep Learning with R, Second Edition

appendix Python primer for R users

You may find yourself wanting to read and understand some Python, or even port some Python to R. This guide is designed to enable you to do these tasks as quickly as possible. As you’ll see, R and Python are similar enough that this is possible without necessarily learning all of Python.
