Display the terms of a Fibonacci series Python Program
# Program to display the Fibonacci sequence up to n-th term nterms = int(input("How many terms ? ")) # first two terms n1, n2 = 0, 1 count = 0 # check if the number of terms is valid if nterms <= 0: print("Please enter a positive integer") # if there is only one term, return n1 elif nterms == 1: print("Fibonacci sequence upto",nterms,":") print(n1) # generate fibonacci sequence else: print("Fibonacci sequence:") while count < nterms: print(n1) nth = n1 + n2 # update values n1 = n2 n2 = nth count += 1
Output:
How many terms ? 5 Fibonacci sequence: 0 1 1 2 3 >>>
How many terms ? 11 Fibonacci sequence: 0 1 1 2 3 5 8 13 21 34 55 >>>
