Python Program to Display Fibonacci Sequence Using Recursion

Fibonacci sequence:

A Fibonacci sequence is a sequence of integers which first two terms are 0 and 1 and all other terms of the sequence are obtained by adding their preceding two numbers.

For example: 0, 1, 1, 2, 3, 5, 8, 13 and so on...

See this example:

def recur_fibo(n):
   if n <= 1:
       return n
   else:
       return(recur_fibo(n-1) + recur_fibo(n-2))
# take input from the user
nterms = int(input("How many terms? "))
# 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))

Output:
