Here's the Python code I have so far (along with a picture):

import sys import turtle

turtle.setup(400,400) wn = turtle.Screen() wn.title("Circle Program") wn.bgcolor("white")

tess = turtle.Turtle() tess.color("gray") tess.pensize(2) tess.hideturtle()

# x is number of sides, y is probability def circle(x): for value in range(x): tess.dot() tess.forward(30) # left 22.5 degrees tess.left(360 / x) # y is connect dots/lines w/ probability?

wn.mainloop()

tess.penup() # works in IDLE Shell # circle(16)

if __name__ == "__main__": try: x = int(sys.argv[1]) # y = int(sys.argv[2]) # x is number of sides, y is probability circle(x) except Exception as e: print("Invalid command line entry. Please try again.")

Here's the output:

It appears I answered part of the question: plotting symmetric points of a circle with the first command-line argument. That's as far as I can solve for this assignment. I appreciate your coding assistance to produce the assignment's result!

1.5.19 Compose a program that takes as command-line arguments an integer n and a float p (between 0 and 1), plots n equally spaced points of size on the circum- ference of a circle, and then, with probability p for each pair of points, draws a gray line connecting them. 16 .125 16.25 16.5 16 1.0 import sys import turtle turtle.setup (400, 400) wn = turtle.
