Variables! In lawman term

A variable in Python is an entity or a container that is used to store data provided by the user. Or, we can say, it is a reserved memory location to store values. Some of the key features of variables are discussed below.

• Variable is stored in RAM.

• Value saved inside a variable is lost once the kernel is restarted.

• Name of the variable is case-sensitive.

• Variable name can be anything. But, the name should start with numbers or special characters except for the underscore(_).

• Variable name should not be a Python keyword and no space is allowed while naming a variable.

Python provides a cool feature in which you can type the name of the variable followed by a dot(.) and press the tab. This will list all the functions available for that variable in Python.
