What is a Variable in Python?

What is a Variable in Python?

A variable is simply a name the programmer uses to refer to the computer storage location. The term variables are used because the value stored in the variable may change or vary. The computer keeps track of the actual memory address that corresponds to each name the programmer assigns.

Variables and constants are objects that a program manipulates. A variable is the name of the memory location, which stores a value. Variables can be compared to empty containers - They can be filled by the user or programmer with values. To use a variable, it must be defined by giving its type and identifier. The type of variable shows the kind of value the variable will store. The identifier of a variable is also the name of the variable. Consider the following examples below.
