-### factorial
-
-Calculates the factorial of a number.
-
-Use recursion. If `num` is less than or equal to `1`, return `1`. Otherwise, return the product of `num` and the factorial of `num - 1`. Throws an exception if `num` is a negative or a floating point number.
-
-```python
-def factorial(num):
-    if not ((num >= 0) & (num % 1 == 0)):
-        raise Exception(
-            f"Number( {num} ) can't be floating point or negative ")
-    return 1 if num == 0 else num * factorial(num - 1)
-```
-``` python
-factorial(6) # 720
