2021-04-11 NumPy Arrays Are Faster Than Lists. Before we discuss a case where NumPy arrays become slow like snails, it is worthwhile to verify the assumption that NumPy arrays are generally faster than lists. To do that, we will calculate the mean of 1 million element array using both NumPy and lists. The array is randomly generated.

PYTHON LISTS VS. ARRAYS: HOW TO CHOOSE BETWEEN THEM
The list type is always available as part of Python’s built-ins. With arrays, there are several types we can talk about. Two built-in types are the bytes type, an immutable sequence of bytes, and the bytearray type, a mutable array. Other arrays can also be created where the item size is not just a single byte, but matches well known C types.

WHAT’S THE DIFFERENCE BETWEEN ARRAYS AND LISTS IN PYTHON?
2021-05-09 In Python, lists are the default list-like data structure which happens to be mutable, dynamically-sized, and heterogeneous (sort of). In contrast, Python has support for arrays through the array module, but these arrays aren’t “true” arrays in the theoretical sense. As a result, they’re mutable, dynamically-sized, and homogenous.
