return
In Python, the return keyword exits a function and returns a value back to the caller. It allows you to send results back from a function so that you can use them elsewhere in your program. If no value is specified, return will return None by default.
Python return Keyword Examples
Here’s an example to illustrate how the return keyword is used in Python:
>>> def add(a, b):
... return a + b
...
>>> result = add(3, 5)
>>> result
8
In this example, the add() function takes two numeric values as arguments and returns their sum. The return keyword sends the result of a + b back to where the function was called and stores it in the variable result, which you can access in your code.
Python return Keyword Use Cases
- Returning results from a function to be used in further computations or operations
- Exiting a function early if a certain condition is met
- Returning multiple values from a function using tuples
- Implementing recursive functions
