Mar 8, 2013 · Here is how I would solve the problem. I would define a function to calculate the n th ter om of the fibonacci sequence as follows. def fibo(n): if n<=2: return 1 else: res = fibo(n-1) + …

This is a closed expression for the Fibonacci series that uses integer arithmetic, and is quite efficient. fib = lambda n:pow(2<<n,n+1,(4<<2*n)-(2<<n)-1)%(2<<n ...

Feb 18, 2014 · I have a problem about making a fibonacci sequence to a list, I'm just new to python someone help me please. This is my code. I know this is looking wrong or something …

Apr 5, 2013 · Non-recursive solution. def fib(n): cur = 1 old = 1 i = 1 while (i < n): cur, old, i = cur+old, cur, i+1 return cur for i in range(10): print(fib(i))

Feb 26, 2019 · According to the Fibonacci formula, here's a way to get the nth member of the Fibonacci sequence. This function doesn't use loops nor recursion (recursions are horrible in …

I need to make a program that asks for the amount of Fibonacci numbers printed and then prints them like 0, 1, 1, 2... but I can't get it to work. My code looks the following: a = int(raw_input('Give

A close practical example is the Fibonacci sequence. I reasonably searched hard through available python code for this sequence. There were tons, most often too cryptic for my basic …

Nov 13, 2017 · sum of the even numbers of the numbers below 4,000,000 in the Fibonacci sequence. Your code is summing the even numbers from the first four million Fibonacci …

Aug 11, 2013 · I'm working on Project Euler problem 2: the one about the sum of the even Fibonacci numbers up to four million. My code: def Fibonacci(n): if n == 0: return 0 elif n == 1: r...

Jan 22, 2012 · Better method of generating Fibonacci numbers. I believe this is the best (or nearly the best) solution: def fibo(n): a, b = 0, 1 for i in xrange(n): yield a a, b = b, a + b This is a …
