"""
Write a Python program that generates a list containing integers of random values. The program should take in user inputs for the list length and range of integer values. User-defined functions should be used in the program. The program should print out:

1. The generated list
2. List length
3. Largest integer
4. Smallest integer
5. Total sum of the integers in the list
6. Average of the integers in the list

The following demonstrates an example of an output:

Please enter the length for the list: 10
Please enter the lower bound for the range of integer values: -10

Please enter the upper bound for the range of integer values: 90
Sequence: [88, 36, 27, 59, 27, 8, 54, 59, 68, -4]

List length: 19
Largest integer: 88
Smallest integer: -4
Sum: 422
Average: 42.2
