This post shows you how to use arrays in Python and why this data structure is so useful. A foundational skill for data science, coding, and more!

What’s more, there is a separate array type in Python. The Python array is designed to emulate the behavior of an array in C, and it’s meant chiefly to allow Python to work with C arrays.

Any functions that accept a NumPy array as an argument should be properly typed, so that Cython knows how to interpret the argument as a NumPy array (fast) rather than a generic Python object (slow).
