Truncatable Prime Numbers

Challenge summary:

TRUNCATABLE PRIMES [CODING CHALLENGE]

A prime number without zero digits is called right truncatable if all numbers obtained by successively removing the rightmost digits are prime

Example: 239 is right truncatable 239 => 23 => 2 all of them primes

The first few are 2, 3, 5, 7, 23, 29, 31, 37, 53, 59, 71, 73, 79, 233, 239, 293, 311, 313, 317, 373, 379, 593, 599

A prime number without zero digits is called left truncatable when removing leftmost digits the obtained numbers are all primes

Example: 167 is left truncatable 167 => 67 => 7

The first few are 2, 3, 5, 7, 13, 17, 23, 37, 43, 47, 53, 67, 73, 83, 97, 113, 137, 167, 173
