Local Variable

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

The output is:

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