Average
Write a python program that reads 4 numbers from the user and prints the average of the numbers. Note, this program could be written without reusing or updating any variables, but for the sake of practice, write the program using only one variable to compute the sum.
Example
Enter a number:
1.0
Enter a number:
2.0
Enter a number:
3.0
Enter a number:
4.0
The average is 2.5
