NumPy Arrays for Beginners: A Better Alternative...

NumPy is a highly popular Python package. One of its best features is the NumPy array (officially known as ndarray). You can think of it as a cleaner, much faster version of a standard Python list. Although NumPy arrays resemble Python lists, they offer a significant advantage: you can perform mathematical operations on the entire array at once. These operations are simple to write and execute very efficiently. Example Suppose you have two lists: heights = [2.40, 3.21, 1.34, 3.45] weights = [45.
