# Test to see how notebook functions in deepnote.
# AUTHOR:Your Name Team 4 Group
# COURSE: ISTM 615
# PROGRAM: Team Project chapter 6
# PURPOSE: Create a program to tell whether a number is prime or not and list the factors.
# INPUT: The data collected will be an integer from the user.
# PROCESS: The program will store the code that gets the user input and displays output in the main function.
# The program will display an eror code if the number entered is not in range.
# The program will store the code that checks whether the number prime or not using an increment counter.
# The program witll list the factors of the number if it is not prime.
# The program will ask the user if they want to play again.
# Recall main function to run program
# OUTPUT: Prime Number Checker
# Please enter an integer between 1 and 5000: 5
# 5 is a prime number.
# Try again? (y/n): y
# Please enter an integer between 1 and 5000: 6
# 6 is NOT a prime number.
# It has 4 factors: 1 2 3 6
# Try again? (y/n): y
# Please enter an integer between 1 and 5000: 200
# 200 is NOT a prime number.
# It has 12 factors: 1 2 4 5 8 10 20 25 40 50 100 200
# Try again? (y/n): n
# Bye!
# HONOR CODE: On my honor, as an Aggie, I have neither given
# nor received unauthorized aid on this academic work.

529 is NOT a prime number
It has 3 factors: [1, 23, 529]
256 is NOT a prime number
It has 9 factors: [1, 2, 4, 8, 16, 32, 64, 128, 256]
