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 ...
