fibonacci number syntax in python code example

Example 1: fibonacci series using recursion in python

# Python program to display the Fibonacci sequence

def recur_fibo(n):
   if n <= 1:
       return n
   else:
       return(recur_fibo(n-1) + recur_fibo(n-2))

nterms = 10

# check if the number of terms is valid
if nterms <= 0:
   print("Plese enter a positive integer")
else:
   print("Fibonacci sequence:")
   for i in range(nterms):
       print(recur_fibo(i))

Example 2: code fibonacci python

# Program to display the Fibonacci sequence forever

def fibonacci(i,j):
  print(i;fibonacci(j,i+j))
fibonacci(1,1)
