4- what is variable in python?

In Python, a variable is a symbolic name that refers to a value stored in the computer's memory. It acts as a container or a placeholder for data, allowing you to store, retrieve, and manipulate information within your programs.
Here are key characteristics of Python variables:
Assignment: Variables are created and assigned values using the assignment operator =. For example, my_variable = 10 creates a variable named my_variable and assigns it the integer value 10.
Dynamic Typing: Python is dynamically typed, meaning you do not need to declare the data type of a variable explicitly. The interpreter infers the type based on the value assigned. You can also reassign a variable to a value of a different type later in the code.
