How to print the Fibonacci Series using Python Program

Python Program to print the Fibonacci Series using While Loop

The Fibonacci number series are 0, 1, 1, 2, 3, 5, 8..etc. The logic of the Fibonacci series is as follows:

f0 = 0

f1 = 1

Now the third Fibonacci number 'f' in the series can be obtained by adding the previous two number in the series.

f = f0 + f1

Now we can print the Fibonacci Series up to the user specified range.

n = int(input('How many Fibonacci''s Series to print: '))

f0 = 0
f1 = 1
f = 0

fiblist = [0, 1]

i = 0

if n == 0:

    fiblist = f0

elif n == 1:

    fiblist = f0, f1

else:

    while i < n-2:

        f = f0+f1

        fiblist.append(f)

        f0, f1 = f1, f

        i = i+1

print('The Fibonacci Series between {0} and {1} is: '.format(0, n), fiblist)

Input:

How many Fibonacci's Series to print: 10

Output:

The Fibonacci Series between 0 and 10 is:  [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]

Process finished with exit code 0
