Working the Snake - Python
I finally found my way to (Iron) Python[1][2] - well I did some Python in the beginning of my studies but lost focus after some time. The experience was quite impressive, since development time is greatly reduced by such a dynamic language. I managed to get some small programs running in less then 1 hour and of course I want to share them with you - precious audience. Since these are my first scripts, I assume that they are not quite correct/stable/... - they are simple and not very error-safe (no checking of arguments ) ... The first is some simple factorial program, which tries to find the greatest common divisor ( gcd )of two numbers by employing the fact that gcd (x, y) = gcd (y, r) where r = x mod y. Since I do not know how a scope for loops can be created (scoping a while/for loop) I did the routine recoursively. The second function builds on the first and is allows to ask whether some number x is a prime number by using the simple strategy of finding a gcd within the range of 1...
