System shell commands
Yet another really helpful feature is that you can execute command-line/system shell
functions directly from an IPython prompt or a Notebook cell. To this end you need to use
the ! to indicate that the following command should be escaped to the system shell (or %%!
when a complete cell should be handled that way). As a simple illustration, the following
creates a directory, moves to that directory, moves back, and deletes the directory:
In [ 7 ]: !mkdir python4finance
In [ 8 ]: cd python4finance/
/Users/yhilpisch/python4finance
In [ 9 ]: cd ..
/Users/yhilpisch
In [ 10 ]: !rm -rf python4finance/
IPython provides you with all the functions you would expect from a powerful interactive
development environment. It is often the case that people, beginners and experts alike,
even find their way to Python via IPython. Throughout the book, there are a plentitude of
examples illustrating the use of IPython for interactive data and financial analytics. You
should also consult the book by McKinney (2012), and in particular Chapter 3, for further
information on how to use IPython effectively.
Spyder
While IPython satisfies all of most users’ requirements for interactive analytics and
prototyping, larger projects generally demand “something more.” In particular, IPython
itself has no editor directly built into the application.

For all those looking for a more
traditional development environment, Spyder might therefore be a good choice.
Similar to IPython, Spyder has been designed to support rapid, interactive development
with Python. However, it also has, for example, a full-fledged editor, more powerful
project management and debugging capabilities, and an object and variable inspector as
well as a full integration of the IPython shell version. Within Spyder you can also start a
standard Python prompt session.
The built-in editor of Spyder provides all you need to do Python development. Among
following:
Highlighting
Syntax coloring for Python, C/C++, and Fortran code; occurrence highlighting
Introspection
Powerful dynamic code introspection features (e.g., code completion, calltips, object
definition with a mouse click)
