in python, when a function does not explicitly return a value, it automatically returns `none` by default. however, you can provide a default return value by using the `return` statement with a specified value. this can be useful in situations where you want to ensure that a function always returns a certain value, even if no explicit return statement is encountered.

here's an informative tutorial with a code example to demonstrate python function default return value:

in the code example above:
the `greet` function does not have an explicit return statement, so it returns `none` by default.
the `divide` function checks for division by zero and returns `none` as the default return value in that case.

by specifying a default return value in your function, you can ensure that the function always returns a specific value even if no explicit return statement is provided. this can help improve the predictability and reliability of your code.
