Validating primes

Let's see how to use logic programming to check for prime numbers. We will use the constructs available in logpy to determine which numbers in the given list are prime, as well as finding out if a given number is a prime or not.

Create a new Python file and import the following packages:

import itertools as it
import logpy.core as lc
from sympy.ntheory.generate import prime, isprime

Next, define a function that checks if the given number is prime depending on the type of data. If it's a number, then it's straightforward. If it's a variable, then we must run the sequential operation. To give a bit of background, the method conde is a goal constructor that provides logical AND and OR operations.

The method condeseq is like conde, but it supports the generic iteration of goals:

# Check if the elements of x are prime 
def check_prime(x):
    if lc.isvar(x):
        return lc.condeseq([(lc.eq, x, p)] for p in map(prime, it.count...
