Python como usar o 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]
