# Assign a variable to hold the total number of marbles, start it at 17

# Assign a varibale that will keep track of whose turn it is, start it either as comp or user

# Print the welcome to the game message

# Print the number of marbles in the jar message

# Start a while loop, use the variable that holds the total number of marbles, and keep the loop going until it gets to 0 or below

	# check if the turn is set to comp or user
	# if it is comp
		# assign a variable to hold the computer's choice, use random.randint(1,3) to get a random # between 1 and 3
		# print the computer removed # marbles message
		# switch the turn to user
	# if the turn is user
		# assign a variable to hold the user's choice, and ask the user to choose a # from 1 to 3
		# now check if the users choice is less than 1 or greater 3 than
		# use a while loop, and the 'or' operator, or a list [1,2,3] with the 'not in' operator
			# if the choice is outside of the range assign the variable to a new input asking the user to keep the value between 1 and 3
		# print You removed # marbles message
		# switch the turn to comp
	# After this if else statement, we have a choice of marbles to remove
	# Subtract the choice from the total number of marbles
	# Print there are # marbles left in the jar
	
# The while loop exits here when the number of marbles reaches 0
# Now we need to check who won (who took the last the turn?)
