In python, there is a concept called unpacking values. What it does is, it allows us to assign values to multiple variables together at the same time. I think it is easier to explain this with an example.

In this way we can unpack vales using python. But what happens if the variables and the values do not match? Let us find out.

If the variables are less compared to the values to unpack we will get a ValueError like this.

The next case is having more variables than the values to unpack. In this case we will get a ValueError like this.

There is an alternative to this situation. If we are not sure of the number of values to be unpacked but we know the number of variables required, we can declare any of the variables like ***variable**, which is nothing but a list-like variable. So all the excess values will be stored in this variable as a list.

I hope now you are clear with this concept. We will be using this similar unpacking concept to unpack the many values returned from our function .

**Returning multiple values from a function**

In python, we can return multiple values from a function separated by a comma. Consider the following program where my function will return four values.

def operation(num1, num2): add = num1 + num2 sub = num1 - num2 mul = num1 * num2 div = num1 / num2 return add, sub, mul, div

The **operation()** function will take two numbers and perform addition, subtraction, multiplication, and division operations on them. It returns the result of all these four operations separated by a comma.

We can unpack the values in our main program like this.

value1 = 10 value2 = 5 addition, subtraction, multiplication, division = operation(value1, value2)

The addition variable will have the result of the addition operation, subtraction will have the result of the subtraction operation and so on.

The complete code looks like this.

def operation(num1, num2): add = num1 + num2 sub = num1 - num2 mul = num1 * num2 div = num1 / num2 return add, sub, mul, div value1 = 10 value2 = 5 addition, subtraction, multiplication, division = operation(value1, value2) print(f"addition result is {addition}") print(f"subtraction result is {subtraction}") print(f"multiplication result is {multiplication}") print(f"division result is {division}")

The output of the above code is,

```
addition result is 15
subtraction result is 5
multiplication result is 50
division result is 2.0
```

That is how you will return multiple values from a function and unpack it in your main code.
