How to find axiom of this picture

[DerbyHarrington]

Hey folks. I'm wondering if anyone can help me to find axioms of these pictures somehow

Define "axiom" in this context. Also, what have you tried, or looked up or anything? We aren't here to do the work for you.

Hello, thank you for your reply.
sorry about that. I forgot to show what I've worked. So this is what I've worked :

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77

import turtle   D = 90 L = 10   def iterate(axiom, num=0, initator='F'):     """     Compute turtle rule string by iterating on an axiom     """       def translate(current, axiom):         """         Translate all the "F" with the axiom for current string         """         result = ''         consts = {'+', '-', '[', ']'}         for c in current:             if c in consts:                 result += c                 continue             if c == 'F':                 result += axiom         return result       # Set initator     result = initator     for i in range(0, num):         # For ever iteration, translate the rule string         result = translate(result, axiom)     return result   def draw(axiom, d=D, l=L):     """     Use turtle to draw the L-System     """     stack  = []                 # For tracking turtle positions     screen = turtle.Screen()     screen.bgcolor('black')     screen.setup(width=1000,height=1000,startx = 500,starty=0)     alex   = turtle.Turtle()     alex.pencolor('yellow')     alex.up()     alex.left(90)       alex.setposition(0,-250)     alex.down()     alex.hideturtle()          alex.speed(1)                                         for i in range(len(axiom)):         c = axiom[i]           if c == 'F':             alex.forward(l)           if c == '-':             alex.left(d)           if c == '+':             alex.right(d)           if c == '[':             stack.append((alex.heading(), alex.pos()))                         if c == ']':             heading, position = stack.pop()             alex.penup()             alex.goto(position)             alex.setheading(heading)             alex.pendown()   if __name__ == '__main__':         axiom = "FF-[-F+F+F]+[+F-F-F]"         axiom = iterate(axiom, 5, "F")         draw(axiom, 25, 13)

So using the FF-[-F+F+F]+[+F-F-F] as the axiom and using:

[python]
for i in range(len(axiom)):
c = axiom[i]

if c == 'F':
alex.forward(l)

if c == '-':
alex.left(d)

if c == '+':
alex.right(d)

if c == '[':
stack.append((alex.heading(), alex.pos()))


if c == ']':
heading, position = stack.pop()
alex.penup()
alex.goto(position)
alex.setheading(heading)
alex.pendown()

as the rule will produce this image

So now my lecturer told me to find the axiom of those pictures by applying the same rule.

Thanks you. Sorry for my bad english.
