Mastering IPython 4.0

By: Thomas Bitterman, Dipanjan Deb

Overview of this book

IPython is an interactive computational environment in which you can combine code execution, rich text, mathematics, plots, and rich media. This book will get IPython developers up to date with the latest advancements in IPython and dive deep into interactive computing with IPython. This an advanced guide on interactive and parallel computing with IPython will explore advanced visualizations and high-performance computing with IPython in detail. You will quickly brush up your knowledge of IPython kernels and wrapper kernels, then we'?ll move to advanced concepts such as testing, Sphinx, JS events, interactive work, and the ZMQ cluster. The book will cover topics such as IPython Console Lexer, advanced configuration, and third-party tools. By the end of this book, you will be able to use IPython for interactive and parallel computing in a high-performance computing environment.

Working with cells


Individual cells function very much like the IPython command line, with the slight change that hitting Enter does not cause the cell to be executed, but instead creates a new line to be typed on. In order to execute a cell, there are many options:

  • Alt + Enter runs the current cell and inserts a new one below

  • Ctrl + Enter runs the current cell and does not create a new cell

  • The Cell menu item contains a list of ways to run cells, including Run All

The result of cell execution is very similar to what would be expected from the command line, for example:

Note that the bottom cell contains Markdown text (http://daringfireball.net/projects/markdown/) rather than Python code. Markdown is a plain text formatting syntax meant to be easily convertible to HTML. Why docstrings are in reStructuredText and notebook cells are in Markdown is a mystery. Luckily, they are fairly similar.

Fixing the error in cell 3 allows the code in the next cell to run, which highlights a neat feature: the...
