Need to refer to Value of a key of a dictionary nested within a dictionary

You can find my code at the link below, and you can ignore any commented sections of code (Accept the one in make_grid() ):

# Sends data
class readGrid(object):
    def __init__(self, x, y, boolean, occu):
        self.x = x
        self.y = y
        self.boolean = boolean


# produces the Peg Grid, and outputs it
grid_list = []

list
def make_grid():
    for key, item in list[11]:
        print(item)

        #my_var = readGrid(sub_list[0], sub_list[1], sub_list[2], sub_list[3])
        #grid_list.append(my_var.boolean)
    #print(*grid_list, sep=', ')


make_grid()



#for item in list:
#    if item[11]['onScreen']:
#
#        twoOverKey = str(item['x'] + 2) + str(item['y']);
#        twoOver = list[twoOverKey];
#        if twoOver['occupied'] == False:
#            print("h")
            # do something

What I'm trying to do is print out the Character held in 'onScreen' by for-looping through the dictionary in the make_grid() function. Of course this would be easy if it was a list, but... it's not!
