Chapter 13. Controlling Execution

Python documents (in other words, directly exposes and supports) many of the internal mechanisms it uses. This support may help you understand Python at an advanced level, and lets you hook your own code into such documented Python mechanisms and control them to some extent. For example, "Python built-ins" on page 141 covers the way Python arranges for built-ins to be made implicitly visible. This chapter covers other advanced Python control techniques, while Chapter 18 covers techniques that apply specifically to testing, debugging, and profiling.
