Requirements: 1. Write a function named collatz() that has one parameter named number. If number is • even, then collatz() should print number // 2 and return this value (integer divison). odd, then collatz() should print and return 3* number + 1. 2. This program must use a loop and must not be recursive (i.e., function may not call itself). 3. Write a main function that lets the user type in an integer, and keeps calling the collatz() function on subsequent results until the function returns the value 1. (Remember to define the collatz() function outside the main() function as it is a standalone function. You can however call the collatz() function from inside the main() function.) Hints: An integer number is even if number % 2 == 0, and it's odd if number % 2 == 1. A sample output of the program should look something like this: Enter number: 3 10 5 16 8 ∞4~ L 2 You must use a loop that exits the program only when the returned value is 1. Remember to convert the return value from input() to an integer with the int() function; otherwise, it will be a string value. 1

Question

Hello. I'm using functions in my python code.

I'm not sure how to end the collatz function. Also, there's no output being displayed.

**Requirements:** 1. **Write a function named `collatz()` that has one parameter named `number`.** - If `number` is **even**, then `collatz()` should **print** `number // 2` and **return** this value (integer division). - If `number` is **odd**, then `collatz()` should **print** and **return** `3 * number + 1`. 2. **This program must use a loop and must not be recursive** (i.e., function may not call itself). 3. **Write a main function that lets the user type in an integer, and keeps calling the `collatz()` function** on subsequent results until the function returns the value 1. (*Remember to define the `collatz()` function outside the main() function as it is a standalone function. You can however call the `collatz()` function from inside the main() function.*) **Hints:** - You must use a loop that exits the program only when the returned value is 1. - Remember to convert the return value from `input()` to an integer with the `int()` function; otherwise, it will be a string value. - An integer number is even if `number % 2 == 0`, and it’s odd if `number % 2 == 1`. **A sample output of the program should look something like this:** ``` Enter number: 3 10 5 16 8 4 2 1 ```

```python # Rahma Seid # CSCI 1170-001 # OLA5 # The purpose of this program is... def main(number): number = int(input("Enter number: ")) collatz(number) def collatz(number): if number % 2 == 0: number = number // 2 print(number) return number elif number % 2 == 1: number = number * 3 + 1 print(number) return number main() ``` ### Explanation This Python program seems to be intended to demonstrate the Collatz conjecture process. Here's a breakdown of its components: 1. **Header Comments** - The top comments include details such as the author's name, course information, and assignment number. 2. **Main Function (`main`)** - **Input**: Prompts the user to enter a number with `input()`, and converts it to an integer. - **Process**: Calls the `collatz` function passing the number. 3. **Collatz Function (`collatz`)** - **If Statement**: Checks if the number is even. - If true, it divides the number by 2 and prints the result. - **Elif Statement**: Checks if the number is odd. - If true, it multiplies the number by 3, adds 1, and prints the result. 4. **Program Execution** - The `main()` function is called to start the process. ### Usage - This program will take an input number from the user, perform one iteration of the Collatz function, and print the result. To fully implement the Collatz sequence, a loop would typically be used to continue applying the `collatz` function until the number is reduced to 1.
