Scope and Variables

Scope determines where a variable exists and can be accessed. Understanding scope prevents bugs where variables unexpectedly have wrong values or do not exist when you expect them to. Python has two main scopes relevant to functions: local scope (inside a function) and global scope (outside all functions). Local Variables Variables created inside a function are local to that function. They are created when the function starts running and destroyed when the function finishes. They do not exist outside the function and cannot be accessed from elsewhere: This isolation is intentional and beneficial. Each function has its own private workspace. You can use the same variable name in different functions without conflict because each function has its own local scope. Global Variables Variables cr
