Variables in Python

Variables in python are used to store data values that can be referenced and manipulated in a program. They serve as named containers for storing information such as numbers, strings, lists, or complex objects. Variables are dynamically typed, meaning they can hold values of different types during execution. Declaration and initialization are combined into a single step, where a variable is assigned a value using the assignment operator (`=`). Python variables are case-sensitive and follow naming rules: they must start with a letter or underscore, and subsequent characters can include letters, numbers, and underscores. Variables provide flexibility and facilitate dynamic data manipulation in Python programs.
