ABSTRACT
A data type provides a set of values from which an expression may take its values. The type defines the operations that can be done on the data, the meaning of the data and the way values of that type can be stored. Every variable in Python is considered as an object and follows the standard nomenclature of an alphanumeric name, beginning with a letter or underscore. This chapter includes various datatype usages in Python and the assigning of variable and identifiers. The eval function plays an important role for user inputs and for the print function to print statements as well as the final output of the program.
