Variables store data from "summary" of Python Programming by John M. Zelle
When we write a program, we often need to keep track of information. We use variables to store this information. A variable is a named storage location in the computer's memory where we can store a value. When we create a variable, we give it a name so that we can refer to it later in the program. In Python, we can create a variable by using an assignment statement. An assignment statement has the following form: variable_name = value. The variable name is the name of the variable we are creating, and the value is the value that we want to store in the variable. For example, we can create a variable called 'age' and store the value 25 in it by writing: age = 25. Now whenever we refer to the variable 'age' in our program, Python will know that we are talking about the value 25. Variables can store different types of dat...
