This Python script implements the Collatz Conjecture, also known as the 3n+1 conjecture. The conjecture states that for any positive integer, the sequence will eventually reach 1.
The script contains a function named collatz(number), which takes a positive integer as an argument and prints the Collatz sequence for that number.
The script also contains a loop that prompts the user to input a positive integer. If the input is not a positive integer, the script will print an error message and prompt the user again. If the input is a positive integer, the script will execute the collatz function and break the loop.
To run this script, simply execute it in a Python environment. When prompted, input a positive integer to see the Collatz sequence for that number.
