Week 4 Assignment

Week 4 Repository 

def isHappy(n):
  while True:
    temp = 0

    for i in str(n):
      temp += int(i) ** 2

    n = temp

    if n == 4:
      return False
    elif n == 1:
      return True
  • The isHappy() function is used to determine whether the given number n is a happy number
  • To determine if a number is a happy number, we sum the squares of its digits, which is done by the for loop in the code
  • If a number is not a happy number, it will eventually fall into a endless cycle that includes 4
  • So if a number becomes 4 at some point, we know it's not a happy number and therefore the function returns False
  • According to the definition of happy number, if a number becomes 1, it is a happy number so the function returns True
