How do you return a value from a function?

Answer: The 'return' statement is used in a function to send a value back to the caller after performing the intended calculations or operations. In a Python function, you can use the 'return' statement followed by the value or variable you want to return. For example, in the below 'add_numbers' function, the 'return' statement is used to send the 'result' variable back to the caller:
```python
def add_numbers(a, b):
result = a + b
return result
sum_value = add_numbers(3, 5)
print(sum_value)
```
In this example, the 'add_numbers' function takes two input parameters 'a' and 'b', adds them, and returns the result. The 'sum_value' variable then stores the returned value (8 in this case), which is finally printed out.
