a value sent back from a function
A return value is a value sent back from a function.
A return value is a value that is sent back from a function. It represents the output or result of the function's operation. When a function is called, it may perform some calculations or operations and produce a value as a result. This value can be returned by the function and used in the rest of the program.
To understand return values, you can think of a function as a black box that takes in some input (if necessary) and produces an output. The return value is like the output of that black box. It allows the function to communicate back to the code that called it.
To obtain the return value of a function, you usually need to call the function and assign the result to a variable or use it directly in your code. For example, consider the following function that adds two numbers:
```python
def add_numbers(a, b):
return a + b
```
To use this function, you can call it and store the return value in a variable:
```python
result = add_numbers(3, 5)
```
In this case, the function will return the value 8, and it will be assigned to the `result` variable. You can then use `result` in further calculations or simply print it out.
