What are some tips for optimizing code with NumPy in Python?

To optimize your NumPy code, consider using vectorization instead of loops, leveraging built-in functions, and minimizing memory usage.

Can you explain what vectorization means?

Vectorization refers to the process of converting operations that would typically be performed in a loop into array operations, allowing NumPy to execute them more efficiently.

What built-in functions should I use for optimization?

You should use functions like np.sum(), np.mean(), and np.dot() as they are optimized for performance and can handle operations on entire arrays.

How can I minimize memory usage in NumPy?

To minimize memory usage, use data types that require less memory, such as float32 instead of float64, and consider using views instead of copies.
