It encourages an execute-explore workflow instead of the typical edit-compile-run workflow of many other programming languages. It also provides very tight integration with the operating system’s shell and file system. Since much of data analysis coding involves exploration, trial and error, and iteration, IPython will, in almost all cases, help you get the job done faster. Of course, the IPython project now encompasses a great deal more than just an enhanced, interactive Python shell. It also includes a rich GUI console with inline plotting, a web-based interactive notebook format, and a lightweight, fast parallel computing engine.
