bookLocal Variables in Python: Understanding Function-Level Scope

A local variable is defined inside a function. You cannot access this variable outside the function's definition.


              
123456

            
def greet():
    message = "Aloha"
    print(message, "# local message")

greet()
print(message)  # This line will result in an error
copy

The output is:

Aloha # local message
NameError: name 'message' is not defined

The message variable is not accessible in the global scope; it exists only inside the function. When the function exits, this variable ceases to exist.
