Manually tested locally on Linux with Python 3:

Ran the script: python3 advanced/numpy_tutorial.py and verified printed outputs for array shapes, indexing, arithmetic, dot product, broadcasting, reshape, statistics, unique/sort, random array reproducibility (seeded), and comparisons.

Verified the try/except block demonstrates an invalid-axis error and the script continues without crashing.
