In Python, variables are symbolic names that reference objects. They are created by assigning a value to a name using the equals sign (=). Unlike many other programming languages, Python variables do not need to be declared or defined in advance. They are dynamically typed, meaning a variable can be assigned a value of one type and later re-assigned a value of a different type.

Variable Assignment and Types

Object References and Identity

When you assign a value to a variable, Python creates an object and the variable references that object. For example:
