Question

Please see the snip for the detail.

Note: The polygon have to rotate clockwise in same also counterclock wise have to rotate:

here is my code it have issue it only rotate to clockwise but in same time have to rotate to the counterclockwise too but it not plesase fix it or write from new.

my code:

import turtle as t

import math

class CenteredPolygon:

def __init__(self, n, size, center=(0, 0), pen=None, **kwargs):

self.numsides = n

self.size = size

self.center = center

self.corners = []

self.pen = pen if pen is not None else self.init_pen(**kwargs)

self.draw()

def init_pen(self, **kwargs):

pen = t.Turtle()

for key, value in kwargs.items():

try:

f = getattr(pen, key)

f(value)

except Exception as e:

print(e)

return pen

def set_corners(self) -> list:

p = self.pen

p.pu()

p.goto(self.center)

for i in range(self.numsides):

p.forward(self.size/2)

self.corners.append(p.pos())

p.back(self.size/2)

p.left(360/self.numsides)

p.goto(self.center)

return self.corners

def draw(self):

if not self.corners:

self.set_corners()

p = self.pen

p.pu()

p.goto(self.corners[0])

p.pd()

p.begin_fill()

for i in self.corners:

p.goto(i)

p.goto(self.corners[0])

p.end_fill()

p.pu()

p.goto(self.center)

p.ht()

t.update()

class MyPolygon(CenteredPolygon):

def rotate_by(self, theta, degrees=False):

if degrees:

theta = math.radians(theta)

p = self.pen

p.pu()

p.goto(self.center)

p.rt(theta)

self.corners.clear()

self.draw()

if __name__ == '__main__':

# DO NOT EDIT

t.tracer(100)

import random, time

from random import randint as r

random.seed(3)

n = 3

col = lambda: "#"+"".join(f"{r(0, 255):02x}" for _ in range(3))

polys = []

size = 500

for i in range(6):

polys.append(MyPolygon(n, size, (0, 0), color=col()))

size -= 50

while True:

for a in range(0, 180, 90):

for p in polys:

p.rotate_by(a, degrees=True)

a *= -1

t.update()

time.sleep(0.1)

Here is template.py:

import turtle as t

class CenteredPolygon:

def __init__(self, n, size, center=(0, 0), pen=None, **kwargs):

self.numsides = n

self.size = size

self.center = center

self.pen = pen if pen is not None else self.init_pen(**kwargs)

self.draw()

def init_pen(self, **kwargs):

pen = t.Turtle()

for key, value in kwargs.items():

try:

f = getattr(pen, key)

f(value)

except Exception as e:

print(e)

return pen

def set_corners(self) -> list:

p = self.pen

p.pu()

p.goto(self.center)

for i in range(self.numsides):

p.forward(self.size/2)

self.corners.append(p.pos())

p.back(self.size/2)

p.left(360/self.numsides)

p.goto(self.center)

return self.corners

def draw(self):

if not self.corners:

self.set_corners()

p = self.pen

# p.clear()

p.pu()

p.goto(self.corners[0])

p.pd()

p.begin_fill()

for i in self.corners:

p.goto(i)

p.goto(self.corners[0])

p.end_fill()

p.pu()

p.goto(self.center)

p.ht()

t.update()

class MyPolygon(CenteredPolygon):

def rotate_by(self, theta, degrees=False):

...

if __name__ == '__main__':

# DO NOT EDIT

random.seed(3)

n = 3

col = lambda: "#"+"".join(f"{r(0, 255):02x}" for _ in range(3))

polys = []

size = 500

for i in range(6):

polys.append(MyPolygon(n, size, (0, 0), color=col()))

size -= 50

while True:

for a in range(0, 180, 90):

for p in polys:

p.rotate_by(a, degrees=True)

a *= -1

t.update()

time.sleep(0.1)

Using the given template.py script define the class MyPolygon as prescribed in the diagram below. The rotate method must change the orientation of the drawn shape by a specified angle (given by default in radians).
