Example #1

def is_truncatable(num):
    digits = elib.to_digits(num)
    for i in xrange(1, len(digits)):
        if not elib.is_prime(elib.from_digits(digits[i:])) or \
           not elib.is_prime(elib.from_digits(digits[:i])):
            return False
    return True

Example #2

import elib
import itertools

for i in range(9, 1, -1):
    for perm in itertools.permutations(range(i, 0, -1)):
        n = elib.from_digits(perm)
        if elib.is_prime(n):
            print(n)
            return
