I wrote a short code which outputs the first n numbers of the Fibonacci sequence where n is the value of the passed parameter and each number is printed in a new line. My problem is that the output isn't starting at 0, it starts at 1. How do I also get the 0 in the output?

def fibonacci(n):
    fib1 = 0
    fib2 = 1
    for x in range(0,n):
        print("%d\n" %(fib2), end = " ")
        next = fib1 + fib2 
        fib1 = fib2
        fib2 = next

So this is the output, why are the numbers after the first one moved in? output

def fibonacci(n):
    fib1 = 0
    fib2 = 1
    for x in range(0,n):
        print("%d\n" %(fib1), end = " ")
        next = fib1 + fib2 
        fib1 = fib2
        fib2 = next

Simple print fib1 instead of fib2 at line #5 How do you expect output 0 at start if you printed fib2 which is 1

What Are Fibonacci Retracements and Fibonacci Ratios?, That does not make Fibonacci trading inherently unreliable. However, it can be uncomfortable for traders who want to understand the rationale� Fibonacci doesn’t “mean” anything as a word. It was the name given to Leonardo Pisano a mathematician that lived in Pisa (Italy) between the 12th and the 13th century. He is most known for the Fibonacci sequence, a sequence in which each number is the sum of the two preceding ones 0, 1, 1, 2, 3, 5, … 59 views

You can use:

def fibonacci(n):
    fib1 = 0
    fib2 = 1
    for x in range(0, n):
        print("%d" %(fib1))
        fib1, fib2 = fib2, fib1 + fib2

Alternatively, you can just switch the values of fib1 and fib2 without messing with your code any more.

Fibonacci number, In mathematics, the Fibonacci numbers, commonly denoted Fn, form a sequence, called the way as the sum of one or more distinct Fibonacci numbers in such a way that the sum does not include any two consecutive Fibonacci numbers. The Fibonacci series does have an equation: [math]F_n = F_{n-1} + F_{n-2}[/math] With the additional condition that [math]F_0 = F_1 = 1[/math]. That completely defines the Fibonacci series, and it’s a perfectly good equation. What it isn’t is a closed form formula for the [math]n[/math] th Fibonacci number. For that, you get things like

as mentioned in other examples you can solve your problem .. I am sharing few more ways to do it.. shorter code

 def fibonacci_fun(n):
  a, b = 0, 1
  for x in range(2, n):
    print('%s' % a)
    a, b = b, a+b

 fibonacci_fun(n)

another way using while loop

def fibonacci(n):
  a, b = 0, 1
  while a <= n:
    print(a)
    a, b = b, a+b

fibonacci(n)

Fibonacci Sequence, Fibonacci Sequence. The Fibonacci Sequence is the series of numbers: 0, 1, 1, 2 , 3, 5, 8, 13, 21, 34, The next number is found by adding up the two numbers� This is why the market doesn’t always turn exactly at the Fibonacci levels themselves and instead reverses in between the levels, the market will always reverse at the point where the bank traders have enough orders come into the market to carry out which ever action they wish to take, whether that be placing trades, closing trades or taking profits, the Fibonacci level itself DOES NOT cause the market to reverse.

A Formula for the n-th Fibonacci number, How to find formulae for Fibonacci numbers. How can we compute Fib(100) without computing all the earlier Fibonacci numbers? How many digits does� Fibonacci imagines a biologically unrealistic scenario for the growth of a population. How many pairs of rabbits placed in an enclosed area can be produced in a single year from one pair of rabbits if each pair gives birth to a new pair each month starting with the second month?

That doesn’t necessarily mean they will be “key” levels, but they are probably levels you should at least keep an eye on.

How are Fibonacci numbers expressed in nature?, the number 42. While Fibonacci's rabbit experiment doesn't tackle such deep questions, its answers resonate throughout nature. See more mammal pictures. The Fibonacci sequence is a series of numbers where each number is a sum of the two numbers before it. For example, with the string "0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55," if you add 0 + 1, you get

Comments
  • you can explicitly check for a n==0 and print separately, that's one option.
  • Print fib1 alone before entering the loop.
  • thank you, stupid mistake! lol But another question: why does my output write the 0 and the 1 straight among themselves but all following numbers moved into?
