What feature of IDLE allows for easier debugging of Python scripts?

The interactive shell in IDLE provides a dynamic environment where users can execute Python commands and scripts in real time. This feature is particularly beneficial for debugging because it allows developers to test small snippets of code or function calls immediately. By running code interactively, programmers can observe the results of their changes on-the-fly, making it easier to identify errors and understand how different parts of the program contribute to the overall outcome.

This immediate feedback loop helps in tracing issues and experimenting with different code segments, which can lead to a quicker resolution of bugs.

Although the other features mentioned, such as code completion, color coding, and automatic indentation, enhance the coding experience, they do not directly contribute to the debugging process in the same hands-on manner that the interactive shell does. Code completion can help prevent syntax errors, color coding improves readability, and automatic indentation maintains proper code structure, but the interactive shell uniquely empowers users to run code incrementally and troubleshoot issues effectively.
