1. Enhanced Interactive Interpreter (REPL) Experience

Python’s interactive interpreter (REPL) is a powerful tool for learning and exploring Python, but previous versions had limitations in multi-line editing and code pasting. Python 3.13 significantly improves REPL with:

• Colored Prompts: A more intuitive interactive experience.

• Simplified Commands: REPL-specific commands like exit, clear, and help no longer require parentheses.

• Convenient Multi-line Block Recall: Retrieve previous multi-line code blocks with a single press of the up arrow key, making editing and re-execution easier.

• Improved Code Pasting: Multi-line code blocks can now be pasted and executed without restrictions, greatly enhancing debugging efficiency.
