Fibonacci

Generates a list, containing the Fibonacci sequence, up until the nth term.

• Starting with 0 and 1, use list.append() to add the sum of the last two numbers of the list to the end of the list, until the length of the list reaches n.
• If n is less or equal to 0, return a list containing 0.

def fibonacci(n):
  if n <= 0:
    return [0]
  sequence = [0, 1]
  while len(sequence) <= n:
    next_value = sequence[len(sequence) - 1] + sequence[len(sequence) - 2]
    sequence.append(next_value)
  return sequence

fibonacci(7) # [0, 1, 1, 2, 3, 5, 8, 13]
