Employing array methods and functions
We will now discuss the use of NumPy array methods and functions. In this section, we will look at common ndarray
functions and methods. These features allow you to perform common tasks using a clean, intuitive syntax, going beyond the notion of Pythonic code.
Array methods
NumPy ndarray
functions include methods that facilitate common tasks, such as finding the mean of a dataset or multiple means of multiple datasets. We can sort array rows and columns, find mathematical and statistical measures, and much more. There are so many functions that do so many things! I won't list them all. In the following, we see the functions needed for common administrative tasks, such as interpreting arrays as lists or sorting array contents:

Next, we see common statistical and mathematical methods, such as finding the mean or sum of array contents:

We also have methods for arrays of Boolean values:

Let's see some of these in a Notebook. Import NumPy and create an array of...
