Python Program to Print the Fibonacci Sequence

Here you will learn how to print the Fibonacci Sequence by using while loop. A Fibonacci sequence is the sequence of integers from 0, 1, 1, 2, 3, 5, 8......

The initial two terms are 0 and 1 and rest of the numbers are obtained simply by adding the preceeding two terms.


Python Code

# Program to display the Fibonacci sequence up to n-th term where n is provided by the user # change this value for a different result nterms = 10 # uncomment to take input from the user #nterms = int(input("How many terms? ")) # first two terms n1 = 0 n2 = 1 count = 0 # check if the number of terms is valid if nterms <= 0: print("Please enter a positive integer") elif nterms == 1: print("Fibonacci sequence upto",nterms,":") print(n1) else: print("Fibonacci sequence upto",nterms,":") while count < nterms: print(n1,end=' , ') nth = n1 + n2 # update values n1 = n2 n2 = nth count += 1

Output

Fibonacci sequence upto 10 : 0, 1, 1, 2, 3, 5, 8, 13, 21, 34,.....

So learners see the tutorial and try it by changing the values of num in the program.
