Hi!

Is there a similar construct to python's:

>>> for n in range(2, 10):
=2E..     for x in range(2, n):
=2E..         if n % x =3D=3D 0:
=2E..             print n, 'equals', x, '*', n/x
=2E..             break
=2E..     else:
=2E..         # loop fell through without finding a factor
=2E..         print n, 'is a prime number'
=2E..=20
2 is a prime number
3 is a prime number
4 equals 2 * 2
5 is a prime number
6 equals 2 * 3
7 is a prime number
8 equals 2 * 4
9 equals 3 * 3

thx
Gergo
