Some common data types in python are tuples, arrays, and dictionaries.

Arrays can be implemented in either straight python or using the Numpy scientific computing library. Basically, an array is a sequence of numbers. It can be 1D or 2D as in a matrix, or even ND as in a tensor.

A tuple on the other hand is a non-mutable set of numbers, i.e. once you define it you can’t change it.

A dictionary is like an array, but it has another layer — a key. Think of it like the index to a book. You have the key words associated with numbers, in this case page numbers. It’s basically an association between two parameters.

We use dictionaries in the next post where we discuss a pathway to the ocean from the aerospace universe.
