Variables and Data Types are two important concepts in the Python Programming Language. “Variables” are terms that hold a given piece of data, whether from the user or hard coded in the program. A “Data Type” refers to the category the programmer intends to assign to a particular piece of data.
Variables assigned in a function, including the arguments are called the local variables to the function. The variables defined in the top-level are called global variables.
Variables and Objects. Variables are the basic unit of storage for a program. Variables can be created and destroyed. At a hardware level, a variable is a reference to a location in memory. Programs perform operations on variables and alter or fill in their values.
• variables: places to store data and results during computing • declarations: specify name (and type) of variables, etc. • expressions: operations on variables and constants to produce new

In Python variables, literals, and constants have a “type”. Python knows the difference between an integer number and a string. For example “+” means “addition” if something is a number and “concatenate” if something is a string. >> ddd = 1 + 4. >> print ddd.
Unlike some other languages, Python allows you to store any type of data in any variable. • Other languages - like Java – will restricted the kinds of values you
