Example of Variable in Python

An Example of a Variable in Python is a representational name that serves as a pointer to an object. Once an object is assigned to a variable, it can be referred to by that name. In layman’s terms, we can say that Variable in Python is containers that store values.

Here we have stored “w3wiki”  in a variable var, and when we call its name the stored information will get printed.

Output:

w3wiki

Notes:

• The value stored in a variable can be changed during program execution.
• A Variables in Python is only a name given to a memory location, all the operations done on the variable effects that memory location.

Rules for Python variables

• A Python variable name must start with a letter or the underscore character.
• A Python variable name cannot start with a number.
• A Python variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ).
• Variable in Python names are case-sensitive (name, Name, and NAME are three different variables).
• The reserved words(keywords) in Python cannot be used to name the variable in Python.

Example 

Output:

1 2 5
6 7 8

Python Variable is containers that store values. Python is not “statically typed”. We do not need to declare variables before using them or declare their type. A variable is created the moment we first assign a value to it. A Python variable is a name given to a memory location. It is the basic unit of storage in a program. In this article, we will see how to define a variable in Python.
