Python String Reversal Methods

- Core Concepts
- Python strings are immutable, so reversing in place isn't possible
- Strings are indexable, sliceable, and iterable
- Reversal Methods
- Slicing with negative step (-1) creates reversed copies
- reversed() function returns iterator for reverse string iteration
- .join() with reversed() creates reversed string copies
- Manual reversal possible using loops and recursion
- reduce() function provides functional programming approach
- Advanced Features
- Custom ReversibleString subclass can mimic list.reverse()
- sorted() function sorts strings in reverse order
- Reverse iteration available through reversed() or slicing
- Reverse iteration preserves original string content
- Implementation Details
- Default recursion limit is 1000
- Memory efficiency varies by method choice
- UserString class provides additional string functionality
