這篇文章主要介紹了用python繪制櫻花、玫瑰、圣誕樹代碼實例,需要的朋友可以參考下

今天為大家介紹幾個Python“裝逼”實例代碼，python繪制櫻花、玫瑰、圣誕樹代碼實例，主要使用了turtle庫

Python繪制櫻花代碼實例

動態(tài)生成櫻花

效果圖（這個是動態(tài)的）：

實現(xiàn)代碼

import turtle as T
import random
import time
# 畫櫻花的軀干(60,t)
def Tree(branch, t):
  time.sleep(0.0005)
  if branch > 3:
    if 8 <= branch <= 12:
      if random.randint(0, 2) == 0:
        t.color('snow') # 白
      else:
        t.color('lightcoral') # 淡珊瑚色
      t.pensize(branch / 3)
    elif branch < 8:
      if random.randint(0, 1) == 0:
        t.color('snow')
      else:
        t.color('lightcoral') # 淡珊瑚色
      t.pensize(branch / 2)
    else:
      t.color('sienna') # 赭(zhě)色
      t.pensize(branch / 10) # 6
    t.forward(branch)
    a = 1.5 * random.random()
    t.right(20 * a)
    b = 1.5 * random.random()
    Tree(branch - 10 * b, t)
    t.left(40 * a)
    Tree(branch - 10 * b, t)
    t.right(20 * a)
    t.up()
    t.backward(branch)
    t.down()
# 掉落的花瓣
def Petal(m, t):
  for i in range(m):
    a = 200 - 400 * random.random()
    b = 10 - 20 * random.random()
    t.up()
    t.forward(b)
    t.left(90)
    t.forward(a)
    t.down()
    t.color('lightcoral') # 淡珊瑚色
    t.circle(1)
    t.up()
    t.backward(a)
    t.right(90)
    t.backward(b)
# 繪圖區(qū)域
t = T.Turtle()
# 畫布大小
w = T.Screen()
t.hideturtle() # 隱藏畫筆
t.getscreen().tracer(5, 0)
w.screensize(bg='wheat') # wheat小麥
t.left(90)
t.up()
t.backward(150)
t.down()
t.color('sienna')
# 畫櫻花的軀干
Tree(60, t)
# 掉落的花瓣
Petal(200, t)
w.exitonclick()

      t = heading()
      an = -40 +random()*40
      setheading(an)
      dis = int(800*random()*0.5 + 400*random()*0.3 + 200*random()*0.2)
      forward(dis)
      setheading(t)
      #畫葉子
      pd()
      right(90)
      n = cos(radians(heading()-45))/4+0.5
      pencolor(n*0.5+0.5,0.4+n*0.4,0.4+n*0.4)
      circle(2)
      left(90)
      pu()
      #返回
      t=heading()
      setheading(an)
      backward(dis)
      setheading(t)
  pu()
  backward(l)#退回
bgcolor(0.5,0.5,0.5)#背景色
ht()#隱藏turtle
speed(0)#速度 1-10漸進，0 最快
tracer(0,0)
pu()#抬筆
backward(100)
left(90)#左轉(zhuǎn)90度
pu()#抬筆
backward(300)#后退300
tree(12,100)#遞歸7層
