Factorial

This a problem set for you to work through ^[1]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

to build your skill applying computational thinking to a problem
to assess your knowledge and skills of different programming practices

What is this problem set trying to do[edit]

In this example we are learning about lists attributes like len() and math functions.

The Problem[edit]

Create a function, myFactorial(aNumber) which takes the parameter aNumber being passed and return the factorial of it. For example: if num = 3, then your program should return (3 * 2 * 1) = 6.

If you type print(myFactorial(10)) the result should be 3628800.

How you will be assessed[edit]

Your solution will be graded using the following axis:

Scope

To what extent does your code implement the features required by our specification?
To what extent is there evidence of effort?

Correctness

To what extent did your code meet specifications?
To what extent did your code meet unit tests?
To what extent is your code free of bugs?

Design

To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
To what extent is your code eliminating repetition?
To what extent is your code using functions appropriately?

Style

To what extent is your code readable?
To what extent is your code commented?
To what extent are your variables well named?
To what extent do you adhere to style guide?

def factorial(number):
    if number == 0:
        return 1
    else:
        return number * factorial(number-1)
number=int(input("Enter what number to use factorial on: "))
print(factorial(number))
