added some code to play with grid class object and the argument parsing

import argparse

class grid(object):

	def __init__(self, name):

		self.name = name

		self.grid_options = {}

	def load_grid_options(self):

		self.grid_options = {

			'test1': 0,

			'test2': 1,

		}

	def argparse(self):

		"""

		This function handles the arg parsing of the grid.

		Make sure that every grid_option key/value is included in this, 

		preferably with an explanation on what that parameter will do

		"""

		parser = argparse.ArgumentParser(description='Arguments for the binary_c python wrapper grid')

		# add arguments here

		parser.add_argument('--test1', type=int, help='input for test1')

		parser.add_argument('--test2', type=int, help='input for test2')

		# Load the args from the cmdline

		args = parser.parse_args()

		# Copy current grid_option set

		new_grid_options = self.grid_options.copy()

		# loop over grid_options

		for arg in vars(args):

			# If an input has been given in the cmdline: override the previous value of grid_options

		# Put the new grid options back 

		self.grid_options = new_grid_options.copy()

newgrid = grid('test')

newgrid.load_grid_options()

print(newgrid.grid_options)

newgrid.argparse()

print(newgrid.grid_options)

# Custom set a single value:

newgrid.grid_options['test2'] = 2

print(newgrid.grid_options)

# Custom set multiple values:

newgrid.grid_options.update({

print(newgrid.grid_options)
