5.3 Standalone Python/Sage Scripts

The following standalone Sage script factors integers, polynomials, etc:

#!/usr/bin/env sage -python

import sys
from sage.all import *

if len(sys.argv) != 2:
    print "Usage: %s <n>"%sys.argv[0]
    print "Outputs the prime factorization of n."
    sys.exit(1)

print factor(sage_eval(sys.argv[1]))

In order to use this script, your SAGE_ROOT must be in your PATH. If the above script is called factor, here is an example usage:

bash $ ./factor 2006
2 * 17 * 59
bash $ ./factor "32*x^5-1"
(2*x - 1) * (16*x^4 + 8*x^3 + 4*x^2 + 2*x + 1)
