What do we mean then by infrastructure? In principle, it is those hardware and software components that allow the development and execution of a simple Python script or more complex Python applications.

A complete ecosystem has evolved around IPython that is so successful and appealing that users of other languages make use of the basic approach and architecture it provides. For ex‐ ample, there is a version of IPython for the Julia language.
