# Challenge: Conditionals
**Difficulty:** Easy
**Language:** Python
**Subject:** Control Flow (Conditionals)

## Description
Write a program that checks if a number is positive, negative, or zero.

## Requirements
- Create a variable `num` and assign it a value (e.g., -5).
- Use `if`, `elif`, and `else` to check the value.
- Print "Positive", "Negative", or "Zero" based on the value.

## Hints
- Use `num > 0`, `num < 0`, and `num == 0` for the conditions.
- Remember to use indentation for the code inside the blocks.

## Validation
- **Check:** `python3 -c "import main; print(main.check_num(-5))"`
- **Expected Output:** Negative
