   f = [0] * n
   f[0] = 0
   f[1] = 1
   
   for x in range(2, n):
      f[x] = f[x-1]+f[x-2]

fibonacci series in python

k=0

    j=t 
f = "".join([str(element) for element in z]) #conversion of list to string
l = int(f) #conversion of string to integer

fibonacci series in python

#Using Recursion

how to code fibonacci series in python

def fib(n):
    a, b = 0, 1
    while a < n:
        print(a, end=' ')
        a, b = b, a+b
    print()
