python叠加三角形,用Python tu堆叠三角形

另一个通过冲压而非绘图来更好地生活的例子：from turtle import Screen, Turtle

from random import random

TRIANGLE_EDGE = 100

CURSOR_EDGE = 20

TRIANGLE_HEIGHT = TRIANGLE_EDGE * 3 ** 0.5 / 2

def repeat_triangle(turtle, repetitions):

for _ in range(repetitions):

turtle.color(random(), random(), random())

turtle.stamp()

turtle.forward(TRIANGLE_HEIGHT)

screen = Screen()

otto = Turtle('triangle', visible=False)

otto.penup()

otto.setheading(90)

otto.shapesize(TRIANGLE_EDGE / CURSOR_EDGE)

repeat_triangle(otto, 4)

screen.mainloop()

此外，此代码可能不正确，具体取决于您使用的turtle的变体：

^{pr2}$

Python附带的turtle默认为从0到1的float，如果您想使用从0到255的int，则必须通过以下方式请求：turtle.colormode(255)

对绘图代码进行简单的返工以堆叠三角形可以是：from turtle import Screen, Turtle

from random import randint

def repeat_triangle(t, length):

height = length * 3 ** 0.5 / 2

for _ in range(4):

t.color(randint(0, 255), randint(0, 255), randint(0, 255))

t.begin_fill()

for _ in range(3):

t.fd(length)

t.lt(120)

t.end_fill()

t.sety(t.ycor() + height)

screen = Screen()

screen.colormode(255)

otto = Turtle('turtle')

otto.penup()

repeat_triangle(otto, 100)

screen.mainloop()
