Added error catch in solution template for simplicity

import argparse as ap

def solve1(file=None, verbose=False, solution=0):

    if file:

    try:

        with open(file, 'r') as f:

            pass

    except ValueError:

        pass

    return solution

def solve2(file=None, verbose=False, solution=0):

    if file:

    try:

        with open(file, 'r') as f:

            pass

    except ValueError:

        pass

    return solution
