## Python Conditional: Exercise - 42 with Solution

Write a Python program to calculate the sum and average of n integer numbers (input from the user). Input 0 to finish.

Pictorial Presentation: Sample Solution:

Python Code:

``````print("Input some integers to calculate their sum and average. Input 0 to exit.")

count = 0
sum = 0.0
number = 1

while number != 0:
number = int(input(""))
sum = sum + number
count += 1

if count == 0:
print("Input some numbers")
else:
print("Average and Sum of the above numbers are: ", sum / (count-1), sum)
```
```

Sample Output:

```Input some integers to calculate their sum and average. Input 0 to exit
.
15
16
12
0
Average and Sum of the above numbers are:  14.333333333333334 43.0
```

## Python: Tips of the Day

Function argument unpacking in Python.

Example:

```def tips_func(x, y, z):
print(x, y, z)

tuple_val = (2, 0, 2)
dict_val = {'x': 3, 'y': 2, 'z': 1}
tips_func(*tuple_val)
tips_func(**dict_val)
```

Output:

```2 0 2
3 2 1
