Local 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.
def greet(): message = "Aloha" print(message, "# local message") greet() print(message) # This line will result in an error
The output is:
python
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.
