Python seems fairly pleasant to me. Experimenting with code using the interpreter is straightforward -- even when re-using methods or classes from large codebases -- built-in help and documentation is available in the same interactive environment, and the online reference and API documentation is well-organized and versioned, snappy and quick to search. In the rare situations where something requires especially detailed debugging, the core libraries themselves are open source, and the bug tracker is equally open to help trace down any existing conversations and unexpected results.
