Summary
Explore how Python merges object-oriented and functional programming principles. Understand special methods, flexible function parameters, and the role of functions as objects. Discover context managers for resource handling and how these features improve your programming versatility and code efficiency.
Recall
We’ve touched on a number of ways that object-oriented and functional programming techniques are part of Python:
- Python built-in functions provide access to special methods that can be implemented by a wide variety of classes. Almost all classes, most of them utterly unrelated, provide an implementation for
__str__( )and__repr__()methods, which can be used by the built-instr()andrepr()functions. There are many functions like this where a
