We have a function called avg that takes in a variable number of integer inputs. We have to complete it such that it returns the average of all the input integers.

```
def avg(*nums):
pass
```

This is the function that we need to complete.

The *args is a special syntax in python used to define a variable number of inputs. Having a * before the name of the argument means it is a variable input. All the inputs are available in this argument as a list

avg(1,2,3,4) means that the nums will be [1,2,3,4]. we can use this to calculate the average.

## Code for Python Average Function Hackerrank Solution

```
def avg(*nums):
sum = 0
length = 0
for n in nums:
sum += n
length += 1
return sum/length
print(avg(1,2,3,4,5))
```

### Output:

3.0

## Single Line Code

We can also write the code in a single line using python

```
def avg(*nums):
return sum(nums)/len(nums)
print(avg(1,2,3,4,5))
```

### Output:

3.0
