我必须使用类点绘制一个Sierpinski三角形,但是当我尝试运行该程序时,并不能让我绘制该三角形。我们必须有一个输入函数,用于输入大三角形的三个边的长度(L)和迭代次数(I)。请帮忙!这就是我所拥有的。
import turtle
class point:
def __init__(self, x, y):
self.x = x
self.y = y
def midpoint(self, p2):
return point((self.x + p2.x) / 2, (self.y + p2.y) / 2)
def DrawSierpinskiTriangle(length, iterations):
turn = 0
angle = 60
# Initialize the turtle
turtle.hideturtle()
turle.penup()
turtle.degrees()
# Starting point on the cancas
midpoint = ((self.x + p2.x) / 2, (self.y + p2.y) / 2)
decode = {'-':Left, '+':Right, 'X':Forward, 'H':Forward}
code = 'H--X--X'
# Start the drawing
turtle.goto(point[0], point[1])
turtle.pendown()
turtle.hideturtle()
turt=turtle.getpen()
startposition=turt.clone()
# Get triangle
path = code
length = x
for i in range(0,length):
path = path.replace('X','XX')
path = path.replace('H','H--X++H++X--H')
for i in path:
[turn, point, fwd, angle, turt]=decode[i](turn, point, fwd, angle, turt)
def main():
input("Enter the length of the triangle: ")
input("Enter the number of iterations: ")
main()
最佳答案
A)如果使用python 2.x,则可能要使用raw_input
B)您没有保存输入的值。即
tLength = input("Enter the length of the triangle: ")
C)你从不叫
DrawSierpinskiTriangle
总之,请尝试以下操作,它应该可以使您重回正轨,并且可以开始调试Sierpinski函数
def main():
tLength = input("Enter the length of the triangle: ")
numIter = input("Enter the number of iterations: ")
DrawSierpinskiTriangle(tLength, numIter)
main()
