What are Python Variables?

Simple Python code can be written using data types and values that are exclusively literal or constant. However, when you move into more complex code, the program will need to change data as it executes, which is where variables come into play.

Python variables are essentially names attached to objects. The values of these variables don't need to be defined or declared in advance; they simply need to be identified. Creating a variable is a straightforward process: assign a value using the "=" symbol and then start using it. Whenever that variable is used in a statement or expression, its value will be substituted accordingly.

Many programming languages employ statically typed variables, which are initially assigned a specific data type that subsequently requires any value assigned to it during its existence to have the same data type. Python doesn't work this way, and a variable can be assigned one data type and later have it reassigned, providing a tremendous amount of flexibility to the programmer.
