NumPy-Specific Help Functions

NumPy includes built-in tools for exploring its own documentation. np.lookfor() searches docstrings across all NumPy functions for a keyword, making it invaluable when you know what you want to do but not which function does it. np.info() (or the ? syntax in Jupyter) displays detailed documentation for a specific function. Building the habit of consulting documentation directly from your notebook accelerates learning and reduces context-switching to external resources.
