The EAFP principle in Python stands for "Easier to Ask for Forgiveness than Permission," prioritizing attempting operations directly within try-except blocks rather than checking conditions beforehand. This idiomatic approach ensures cleaner, more maintainable code execution flows.

To improve Python code quality, implement type hints by annotating function signatures and variables with standard typing modules. This practice enhances code clarity, enables static analysis tools to catch type errors early, and makes refactoring more maintainable.

The best way to optimize Python performance for memory efficiency is by leveraging generators for lazy evaluation, defining `__slots__` in classes to prevent dynamic attribute creation, and utilizing efficient string manipulation techniques to reduce overhead.

Context managers handle resource cleanup in Python by using the `with` statement to wrap execution blocks, ensuring files or connections close properly even if errors occur. They provide robust error handling and maintainable resource management.

Use data classes for rapidly creating structured data containers with auto-generated methods like `__init__`, and apply decorators to modify function behavior without altering source code. Both features promote readable, explicit, and maintainable Python application architecture.
