InfoDB:

infodb = [{
            "Name": "John",
            "Favorite Subject": "Taking APs",
            "Top 3 Universities": ["Harvard", "MIT", "Stanford"]
          },
          {
            "Name": "Jon",
            "Favorite Subject": "Taking more APs than John",
            "Top 3 Universities": ["MIT", "Caltech", "Princeton"]
          },
          {
            "Name": "Bob",
            "Favorite Subject": "Physical Education",
            "Top 3 Universities": ["I Shou University", "National Yunlin University Science and Technology", "University of Mazandaran"]
          },
          {
            "Name": "BobbY",
            "Favorite Subject": "Intangible Education",
            "Top 3 Universities": ["California State University--Long Beach", "Worcester Polytechnic Institute", "Oakland University"]
          }
          ]

This is infodb which is a list of dictionaries that stores the data.

InfoDB Loops

def forl():
  for i in range(len(infodb)):
    print_data(i)


def whilel():
  n = 0
  while n < len(infodb):
    print_data(n)
    n += 1
  return


def recursive(n):
  if n >= len(infodb):
    return
  elif n < len(infodb):
    print_data(n)
    return recursive(n + 1)


def recursivel():
  recursive(0)

These are the functions called to display infodb’s data.

Fibonacci Algorithmn:

def fibterm(a, b, n):
  if n == 1:
    return a
  elif n == 2:
    return b
  elif n > 2:
    return fibterm(a, b, n - 1) + fibterm(a, b, n - 2) # recursive to add the previous two terms in the fibonacci sequence

This function returns the specified term of the fibonacci sequence with the non-optional options of choosing the two starting numbers.

Classes:

class Factorial:
  def __call__(self, n):
    if n <= 1:
      return 1
    return n * self(n - 1)

def test():
  fac = Factorial()
  n = random.randint(0, 100)
  print(f"Factorial of {n}:", fac(n))
  n = random.randint(0, 100)
  print(f"Factorial of {n}:", fac(n))
  n = random.randint(0, 100)
  print(f"Factorial of {n}:", fac(n))

The class Factorial is defined and within it the call function is implemented. We have to do fac = Factorial() to convert the class to an object. And then when we call the object, the call function within it is called.
