[Python] how to draw a function from list coords?

I have a list which stores the values of a position that I would like to draw a flag on however the position is stored as A OR G rather than a numerical value which means i am having trouble plotting it (cant plot a letter... ). I think the way about fixing this is to assign each letter to a numerical value which I can then plot as X,Y cords in my draw flag function.

for competitor, direction in random_moves():

if competitor == 'Competitor A':
turtle.penup()
if direction == 'Left':
if positions[0][2] != 'A':
positions[0][0] -= HORIZONTAL
positions[0][2] = chr(ord(positions[0][2]) - 1)
elif direction == 'Right':
if positions[0][2] != 'G':
positions[0][0] += HORIZONTAL
positions[0][2] = chr(ord(positions[0][2]) + 1)
elif direction == 'Up':
if positions[0][3] != 7:
positions[0][1] += VERTICAL
positions[0][3] += 1
elif direction == 'Down':
if positions[0][3] != 1:
positions[0][1] -= VERTICAL
positions[0][3] -= 1

turtle.setpos(positions[0][:2]) #MAKE A = 1
turtle.write('ABC', align='left', font=20)
turtle.dot(20, "blue")
occupied[0].append((positions[0][2], positions[0][3]))


I was also wondering why the turtle.write('ABC', align='left', font=20) and turtle.dot(20, "blue") commands work perfectly fine in the correct location however if I try to call my flag_germany function it draws the flag at 0,0 (not sure why) my draw flag function can be seen below. The stored list values can be seen as: and must be appended based on another random location function

positions = [
[-3*HORIZONTAL, 3*VERTICAL, 'A', 7],
[3*HORIZONTAL, 3*VERTICAL, 'G', 7],
[-3*HORIZONTAL, -3*VERTICAL, 'A', 1],
[3*HORIZONTAL, -3*VERTICAL, 'G', 1]
]

occupied = [ # To store the grid occupied
[('A', 7)],
[('G', 7)],
[('A', 1)],
[('G', 1)]
]


draw flag function:

def flag_germany():
penup()
color("black")
fillcolor("white")
seth(90)

# origin_x = 0
# origin_y = 0

# goto(x, y)
fillcolor("red")
seth(90)
begin_fill()
forward(90 - 4)
right(90)
forward(120 - 4)
right(90)
forward(90 - 4)
right(90)
forward(120 - 4)
right(90)
end_fill()
showturtle()
#goto(origin_x, origin_y)

# Orange Rectangle
# goto(origin_x, origin_y+86)
color("black")
begin_fill()
right(90)
forward(120 - 4)
right(-90)
forward(32 - 4)
left(90)
forward(120 - 4)
end_fill()
# goto(origin_x, origin_y)

# goto(origin_x, origin_y-4)
color("yellow")
begin_fill()
penup()
right(90)
forward(58)
pendown()
right(90)
forward(120-4)
right(90)
forward(32)
right(90)
forward(120-4)
right(90)
forward(30)
end_fill()


I have been playing around with using x and y inputs in my draw flag function however I am currently trying to get it to just draw from the location of the turtle just like the turtle.write('ABC', align='left', font=20) and turtle.dot(20, "blue") commands previously used for testing. Any ideas or pointers as to how I can get my flag drawing in the correct location would be much appreciated thanks for your time in advance. Sorry if I made a bad post im also new.
