A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself. (Boy, that's a mouthful.) In other words, if you want to test if a number in a variable x is prime, then no other number should go into x evenly besides 1 and x. So 2 and 5 and 11 are all prime, but 4 and 18 and 21 are not. If there is a nu…

	def is_prime(x):
	if x < 2:
	return False
	elif x == 2:
	return True
	else:
	for n in range(2, x):
	print n
	if x % n == 0:
	return False

Factorial function written in Python. To calculate the factorial of a non-negative integer x, just multiply all the integers from 1 through x. For example: factorial(4) would equal 4 * 3 * 2 * 1, which is 24. factorial(1) would equal 1. factorial(3) would equal 3 * 2 * 1, which is 6.

	def factorial(n):
	if n == 0:
	return 1
	else:
	return n * factorial(n-1)

CesarNog / digit_sum.py

Created January 20, 2015 18:25

Function that takes a positive integer n as input and returns the sum of all that number's digits. For example: digit_sum(1234) should return 10 which is 1 + 2 + 3 + 4.

	def digit_sum(n):
	total = 0
	numberStringfied = str(n)
	listNumbers = list(numberStringfied)
	for n in listNumbers:
	total += int(n)

	return total

Function written in Python to verify if any number is an integer. An integer is just a number without a decimal part (for instance, -17, 0, and 42 are all integers, but 98.6 is not). For the purpose of this lesson, we'll also say that a number with a decimal part that is all 0s is also an integer, such as 7.0. This means that, for this lesson, y…

	def is_int(x):
	if(x < 0):
	x = abs(x)
	if ((x - int(round(x))) > 0):
	return False
	else:
	return True

Here are some things you can do with Gists in GistBox.

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console
