We Keep Coding

I have this error : raise turtle.Terminator

I hope it run and do not stop.
I'm making Conway's Game of Life,
if my code look stupid, please help me, I'm only 11.
I use the details from wiki, if it's wrong , please tell me.
Thankyou!

I'm totally stuck on this,please help me.

I've reworked your code fragment into what I believe you are trying to do. Avoid eval as it can cause endless problems. Your use of global in this context isn't valid. See if this works for you:
from turtle import Screen, Turtle
class Body:
def __init__(self, positions):
self.cells = []
self.make_body(positions)
# self.a()
# self.Alive(screen)
def make_body(self, positions):
for position in positions:
cell = Turtle(shape='square')
cell.fillcolor('white')
cell.penup()
cell.goto(position)
self.cells.append(cell)
def restart():
start_positions.clear()
y = 250
for _ in range(25):
x = -250
for _ in range(25):
start_positions.append((x, y))
x += 20
y -= 20
start_positions = []
screen = Screen()
screen.setup(550, 550)
screen.bgcolor('black')
screen.tracer(False)
restart()
my_body = Body(start_positions)
screen.tracer(True)
screen.exitonclick()
Since I've turned off tracer() for speed, call screen.update() whenever you're ready for the user to see the most recent changes.

The monitor don't work with digital signal processing

I make a ‘photoplethysmograph’ with Raspberry pi(CM3+) and Maxim sensor(max30102).
I connect between Raspberry pi and Maxim sensor by I2C. I write python program. I want to display ‘photoplethysmograpy’ in canvas.
First, I am success to display that, but noise appear.(program0)
Second, I try to use digital signal processing for removing noise.
sampling frequency: 100Hz
band pass filter :0.1Hz : 10Hz
I write program with band pass filter(progmam1) But, the following error message appear and the program don't move. I want to improve program1. What should I do?
error message:
/usr/lib/python3/dist-packages/scipy/signal/signaltools.py:1344: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.

My define statement will only run once

After my code prints one dot on the screen it doesn't run again. This is what it tells me in the terminal after I close the turtle screen:

You have to assign the new a or use a += 1 and also move some lines inside the while loop to execute them each time:
while True:
if a <= b:
x = random.randint(-300, 301)
y = random.randint(-300, 301)
star(size, x, y, color)
drawer.hideturtle()
a += 1
continue

Nanpy Servo Control

*Nanpy allows for a Raspi to have an Arduino slave through python
Right now I'm having extreme difficulty in using the nanpy Servo package, and I cant get it to run correctly. I'm using it to make a robot that is wirelessly controlled from a computer, this is what I have for code:
from nanpy import (ArduinoApi, SerialManager)
import pygame
from nanpy import Servo
import time
pygame.init()
a=0
d=0
window = pygame.display.set_mode((800,600))
pygame.display.set_caption("Console")
try :
connection = SerialManager()
ard = ArduinoApi(connection = connection)
run = True
except:
print("Connection Failed!")
servoA = Servo(2)
servoD = Servo(4)
while run :
for event in pygame.event.get():
keys = pygame.key.get_pressed()
# if (event.type==pygame.KEYDOWN):
if keys[pygame.K_s] and keys[pygame.K_a]:
a=a-1
servoA.write(a)
elif keys[pygame.K_s] and keys[pygame.K_d]:
d=d-1
servoD.write(d)
elif keys[pygame.K_w]:
a=a+1
d=d+1
servoD.write(d)
servoA.write(a)
elif keys[pygame.K_s]:
a=a-1
d=d-1
servoD.write(d)
servoA.write(a)
elif keys[pygame.K_d]:
d=d+1
servoD.write(d)
elif keys[pygame.K_a]:
a=a+1
servoA.write(a)
elif keys[pygame.K_t]:
run=False
pygame.quit()
This is the error the python shell throws:
Traceback (most recent call last):
File "/home/pi/Desktop/nanpy/RobotCode.py", line 28, in <module>

raise SerialManagerError('Serial timeout!')
nanpy.serialmanager.SerialManagerError: Serial timeout!
How can I fix this, and/or what am I doing wrong?

You need to specify the port of the Arduino. So could you try:
connection = SerialManager(device='/dev/ttyACM0')
or whatever port you are using.

update the configuration file to use the servo and upload it to arduino using the IDE then run this program.
you can find the cfg.h file in nanpy-firmware/nanpy folder.

"pygame.error: display Surface quit" while loading

So I'm making a game to test my programming skills and I'm trying to use pygame but when i try and load a level map it says the surface has quit. I have no idea why.
This is the load code:
def load(self):
print(os.listdir())
file = input('>>> file name = ')
try:
self.Dir = os.getcwd()
path = os.path.join(self.Dir, "maps", file)
data = pickle.load(open(path, 'rb'))
except OSError as error:
print('Not file ', path)
print(error)
else:
self.grid = data[0]
self.blocks = data[1]
Thanks in advance
EDIT:
this is the trace back
Traceback (most recent call last):

pygame.error: display Surface quit
EDIT 2:
This is the loop code where it happens:
(The load command is in the self.keyboard() function.)
def loop(self):
print('looping')
for event in pygame.event.get():
if event.type == pygame.QUIT:
print('quiting :(')
pygame.display.quit()
quit('User quit')
self.screen.fill((237, 237, 237))

self.mos = pygame.mouse.get_pressed()
self.mouse()
self.keyboard()
#screen.blit(player,player.pos)
self.blocks.draw(self.screen)
self.extraLoop()
pygame.display.flip()
print('done looping')

You can't pickle a Surface object.
If you want to pickle an object that contains a Surface, remove it before saving it to disk; and store the name of the image file or a string representation of the Surface instead in the object.
