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!

Numba translates Python-interpreted code into machine-native code, with specializations for things like NumPy. Loops in Python over NumPy arrays can be optimized automatically this way.

When you call the Cython function in your Python code, send the entire NumPy array object as an argument for that function call. Perform all the iteration over the object in Cython .
