Data types are a sort of classification, helping you to subdivide values into groups. They can also be seen as a data storage format containing a specific type or range of values. These types can be numbers – with or without a floating point, vectors or strings, for example. When computer programs store data in variables, each variable must be assigned a specific data type. Some programming languages can automatically assign a variable’s data type when the initial data is entered into the variable. Python is one of these languages.
