NumPy Practice Exam
NumPy (Numerical Python) is an open-source library used for numerical
and scientific computing in Python. It provides support for large,
multi-dimensional arrays and matrices, along with a collection of
high-level mathematical functions to operate on these arrays. NumPy is
the foundation for many other scientific libraries in Python, such as
pandas, SciPy, and scikit-learn. Its ability to efficiently perform
operations on large datasets makes it essential for data analysis,
machine learning, and other computational tasks.
