turtle-graphics

I need to figure out how to control the self._newline(), in turtle.py. I found out about this during my python Mandelbrot set program, when it started doing weird things; see Why is turtle lightening pixels? for more details. However, when I tried to make an extremely similar program that graphed the tangent of complex numbers, the same thing did not happen...but the program slowed down considerably over time. Basically, I am asking 3 questions: What is the difference between these programs that causes this discrepancy? (intellectual inquiry) How do I activate/stop self._newline()? (Necessary,

So I've been working on a few games in Python (battleships, tic-tac-toe etc.) and this week's project is Snake. I've got a basic set-up going; the snake can move and eats the food but I haven't programmed in collision detection or going off the edge yet. The problem is response time. If you run the code below, you'll see that the snake responds to key presses, but not for a couple of - I'll call them frames - after the press. I don't quite understand how the listen() method works; am I using it properly? If not, how should I use it, and if so, how can I fix the delay? I know about Pygame, but

I am trying to write a Python turtle program that draws a Spirograph and I keep getting this error: Traceback (most recent call last): File "C:\Users\matt\Downloads\spirograph.py", line 36, in <module> main() File "C:\Users\matt\Downloads\spirograph.py", line 16, in main spirograph(R,r,p,x,y) File "C:\Users\matt\Downloads\spirograph.py", line 27, in spirograph spirograph(p-1, x,y) TypeError: spirograph() missing 2 required positional arguments: 'x' and 'y' >>> This is the code: from turtle import * from math import * def main(): p= int(input("enter p")) R=100 r=4 t=2*pi x= (R-r)*cos(t)-(r+p)

I am trying to fill the color in these squares: Right now the turtle only fills the corners of theses squares, not the entire square. Here is my code: import turtle import time import random print ("This program draws shapes based on the number you enter in a uniform pattern.") num_str = input("Enter the side number of the shape you want to draw: ") if num_str.isdigit(): squares = int(num_str) angle = 180 - 180*(squares-2)/squares turtle.up x = 0 y = 0 turtle.setpos(x,y) numshapes = 8 for x in range(numshapes): turtle.color(random.random(),random.random(), random.random()) x += 5 y += 5 turtle

this is my fist time using the turtle module in python but i can't seem to import it? Here's my code: from turtle import * pen1 = Pen() pen2 = Pen() pen1.screen.bgcolour("#2928A7") and here is the error I get: Traceback (most recent call last): File "C:\Python34\Python saves\turtle.py", line 2, in <module> from turtle import * File "C:\Python34\Python saves\turtle.py", line 5, in <module> pen1 = Pen() NameError: name 'Pen' is not defined Can anyone tell me what I did wrong? The problem is that you've named your program "turtle.py". So when Python sees the statement from turtle import * the

I have a homework assignment, and I have to make four different turtles move like they are planets around the sun. I have it all written, its just a matter of making the turtles draw at the same time. I was wondering if there was a relatively easy way to make them start around the same time (within reason)? Anyway, here's the code: def planets(): """simulates motion of Mercury, Venus, Earth, and Mars""" import turtle mercury = turtle.Turtle() venus = turtle.Turtle() earth = turtle.Turtle() mars = turtle.Turtle() mercury.shape('circle') venus.shape('circle') earth.shape('circle') mars.shape(
