The technique in the above example has the drawback that it doesn’t scale well. If you have multiple arguments that can take values of different data types, then your implementation can soon become a nightmare. So, this technique is considered an anti-pattern in Python....

experiment with more visually interesting output, you should take a look at the turtle module, which implements so-called turtle graphics. 一个简单案例 AI检测代码解析 import numpy as np import cv2 as cv import turtle import time import math turtle.pensize(math.sqrt(5)) turtle.pencolor("black"...
Problem 3: Turtle graphics and drawSquare 这个问题要求使用现有的turn和forward,画一个正方形,就走两步转90度最后转出个正方形就可以了 Problem 5: Drawing polygons 需要用到calculateRegularPolygonAngle()和drawRegularPolygon()。calculateRegularPolygonAngle()是给正多边形边数,计算正多边形内角1 ...
