Fibonacci Series

Fibonacci Series is a list of numbers in which one number on the series is the sum of the previous two numbers.

def fibonacci(end=None, start=0, inclusive=True, length=None):
    ...

Installation and usage

pip install py-fibonacci

from fibonacci import fibonacci

e.g. fibonacci(39) -> returns a list, you may assign it to a variable or print it.

This python package of fibonacci series, provides two use cases:

1. With an 'end' number argument:: so it is possible to list the fibonacci series up to that number and start (default: 0) number argument is optional. An optional boolean inclusive (default: True) argument makes the end number inclusive or exclusive.

examples:

fibonacci(39) 
    -> only end number is given. there are several fibonacci numbers upto 39 starting at 0.

fibonacci(39, 3) 
    -> end and start numbers are given. there are several fibonacci numbers upto 39 starting at 3.

fibonacci(39, 3, False) 
    -> end, start numbers and inclusive=False are given. there are several fibonacci numbers upto 39 (exclusive) starting at 3.

2. With a 'length' number argument:: so it is possible to set the length of the series and start (default: 0) number argument is optional.

examples:

fibonacci(length=20) 
    -> only length of the series is given. there are 20 fibonacci numbers starting at 0.

fibonacci(start=5, length=20) 
    -> start number and length of the series is given. there are 20 fibonacci numbers starting at 5.
