Variables in Python

Variables in Python Programming

In programming , a "variable" is a container that stores the value of data in the system's memory. The saved value can be specified using the variable name. Data stored in a variable is assigned to the Python program notification statement = assignment operator.

Eg : x = 2021

• A variable name cannot start with a number
• A variable name must start with a letter or the underscore (_) character
• A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _)
• Variable names are case-sensitive
