Cython has a feature named typed memoryviews that gives you direct read/write access to many types of objects that work like arrays. That includes—you guessed it—NumPy arrays.

If an array has 10 elements then the last number will be 9 (0-9). ... Arrays in Python differ from other programming languages as it uses lists instead of arrays.

Fortunately, Python has a vast array of built-in features that can help you write code that is elegant, concise, and expandable, the kind of characteristics you expect from a professional programmer.

As you can guess, arrays don’t have to all contain the same type of value. And their definitions can span multiple lines if needed. In Python, arrays map directly to lists.
