11.9. Glossary
- chatterbox function
- A function which interacts with the user (using
input or print) when
it should not. Silent functions that just convert their input arguments into
their output results are usually the most useful ones.
- composition (of functions)
- Calling one function from within the body of another, or using the
return value of one function as an argument to the call of another.
- dead code
- Part of a program that can never be executed, often because it appears
after a
return statement.
- fruitful function
- A function that yields a return value instead of
None.
- incremental development
- A program development plan intended to simplify debugging by adding and
testing only a small amount of code at a time.
- None
- A special Python value. One use in Python is that it is returned
by functions that do not execute a return statement with a return argument.
- return value
- The value provided as the result of a function call.
- scaffolding
- Code that is used during program development to assist with development
and debugging. The unit test code that we added in this chapter are
examples of scaffolding.
- temporary variable
- A variable used to store an intermediate value in a complex
calculation.
