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:

1. def recur_fibo(n):  
2.    if n <= 1:  
3.        return n  
4.    else:  
5.        return(recur_fibo(n-1) + recur_fibo(n-2))  
6. # take input from the user  
7. nterms = int(input("How many terms? "))  
8. # check if the number of terms is valid  
9. if nterms <= 0:  
10.    print("Plese enter a positive integer")  
11. else:  
12.    print("Fibonacci sequence:")  
13.    for i in range(nterms):  
14.        print(recur_fibo(i))  

Output:
