Python Integer Sequences

Developed and maintained by Tyler R. Drury,

This project is a pure python package, allowing users to conveniently represent and generate common integer sequences, including:

• Factorials
• Prime numbers
• Catalan numbers
• Horadam numbers
• Padovan numbers
• Hofstadter numbers
• Collatz numbers
• Pronic numbers
• Lazy Caterer and Cake Numbers
• Geometric numbers(polygonal, polyhedral)

Target Platform

Python 3.6, 64-bit

Use

from integerSequence import Horadam
from integerSequence import Fibonacci as fib
from integerSequence import getPrimes

p = getPrimes(1000) #calculate all primes up to 1000
print(p)

h = Horadam(2,3,1,2)    #unnamed Horadam sequence
s = h.series(10)
print(s)

s = fib.series(20)
print(s)
