python 实现漂亮的烟花，樱花，玫瑰花

显着无聊收集了下用python绘制烟花，绘制樱花，烟花+樱花，飘零雪花，玫瑰花的python绘制代码，可以来练手什么的哦。

同时python实现八音符，坦克大战，贪吃蛇，FlappyBird等都可以参考哦=> code

一、python实现烟花

效果图：

代码如下 ：

import tkinter as tk from PIL import Image, ImageTk from time import time, sleep from random import choice, uniform, randint from math import sin, cos, radians # 模拟重力 GRAVITY = 0.05 # 颜色选项（随机或者按顺序） colors = ['red', 'blue', 'yellow', 'white', 'green', 'orange', 'purple', 'seagreen', 'indigo', 'cornflowerblue'] ''' particles 类 粒子在空中随机生成随机，变成一个圈、下坠、消失 属性: - id: 粒子的id - x, y: 粒子的坐标 - vx, vy: 在坐标的变化速度 - total: 总数 - age: 粒子存在的时长 - color: 颜色 - cv: 画布 - lifespan: 最高存在时长 ''' class Particle: def __init__(self, cv, idx, total, explosion_speed, x=0., y=0., vx=0., vy=0., size=2., color='red', lifespan=2, **kwargs): self.id = idx self.x = x self.y = y self.initial_speed = explosion_speed self.vx = vx self.vy = vy self.total = total self.age = 0 self.color = color self.cv = cv self.cid = self.cv.create_oval( x - size, y - size, x + size, y + size, fill=self.color) self.lifespan = lifespan def update(self, dt): self.age += dt # 粒子范围扩大 if self.alive() and self.expand(): move_x = cos(radians(self.id * 360 / self.total)) * self.initial_speed move_y = sin(radians(self.id * 360 / self.total)) * self.initial_speed self.cv.move(self.cid, move_x, move_y) self.vx = move_x / (float(dt) * 1000) # 以自由落体坠落 elif self.alive(): move_x = cos(radians(self.id * 360 / self.total)) # we technically don't need to update x, y because move will do the job self.cv.move(self.cid, self.vx + move_x, self.vy + GRAVITY * dt) self.vy += GRAVITY * dt # 移除超过最高时长的粒子 elif self.cid is not None: cv.delete(self.cid) self.cid = None # 扩大的时间 def expand (self): return self.age <= 1.2 # 粒子是否在最高存在时长内 def alive(self): return self.age <= self.lifespan ''' 循环调用保持不停 ''' def simulate(cv): t = time() explode_points = [] wait_time = randint(10, 100) numb_explode = randint(6, 10) # 创建一个所有粒子同时扩大的二维列表 for point in range(numb_explode): objects = [] x_cordi = randint(50, 550) y_cordi = randint(50, 150) speed = uniform(0.5, 1.5) size = uniform(0.5, 3) color = choice(colors) explosion_speed = uniform(0.2, 1) total_particles = randint(10, 50) for i in range(1, total_particles): r = Particle(cv, idx=i, total=total_particles, explosion_speed=explosion_speed, x=x_cordi, y=y_cordi, vx=speed, vy=speed, color=color, size=size, lifespan=uniform(0.6, 1.75)) objects.append(r) explode_points.append(objects) total_time = .0 # 1.8s内一直扩大 while total_time < 1.8: sleep(0.01) tnew = time() t, dt = tnew, tnew - t for point in explode_points: for item in point: item.update(dt) cv.update() total_time += dt # 循环调用 root.after(wait_time, simulate, cv) def close(*ignore): """退出程序、关闭窗口""" global root root.quit() if __name__ == '__main__': root = tk.Tk() cv = tk.Canvas(root, height=400, width=600) # 选一个好看的背景会让效果更惊艳！ image = Image.open("./image.jpg")//这里自己选择好背景图片哦 photo = ImageTk.PhotoImage(image) cv.create_image(0, 0, image=photo, anchor='nw') cv.pack() root.protocol("WM_DELETE_WINDOW", close) root.after(100, simulate, cv) root.mainloop()

二、动态樱花

效果如下：

代码如下：

import turtle as T import random import time # 画樱花的躯干(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) # 绘图区域 t = T.Turtle() # 画布大小 w = T.Screen() t.hideturtle() # 隐藏画笔 t.getscreen().tracer(5, 0) w.screensize(bg='wheat') # wheat小麦 t.left(90) t.up() t.backward(150) t.down() t.color('sienna') # 画樱花的躯干 Tree(60, t) # 掉落的花瓣 Petal(100, t) w.exitonclick()

三、烟花配合樱花齐放

import turtle import random import time from PIL import Image, ImageTk # from time import sleep import tkinter as tk from time import sleep from random import choice, uniform, randint from math import sin, cos, radians # 模拟重力 GRAVITY = 0.05 # 颜色选项（随机或者按顺序） colors = ['red', 'blue', 'yellow', 'white', 'green', 'orange', 'purple', 'seagreen', 'indigo', 'cornflowerblue'] # 画樱花的躯干(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) class Particle: def __init__(self, cv, idx, total, explosion_speed, x=0., y=0., vx=0., vy=0., size=2., color='red', lifespan=2, **kwargs): self.id = idx self.x = x self.y = y self.initial_speed = explosion_speed self.vx = vx self.vy = vy self.total = total self.age = 0 self.color = color self.cv = cv self.cid = self.cv.create_oval( x - size, y - size, x + size, y + size, fill=self.color) self.lifespan = lifespan def update(self, dt): self.age += dt # 粒子范围扩大 if self.alive() and self.expand(): move_x = cos(radians(self.id * 360 / self.total)) * self.initial_speed move_y = sin(radians(self.id * 360 / self.total)) * self.initial_speed self.cv.move(self.cid, move_x, move_y) self.vx = move_x / (float(dt) * 1000) # 以自由落体坠落 elif self.alive(): move_x = cos(radians(self.id * 360 / self.total)) # we technically don't need to update x, y because move will do the job self.cv.move(self.cid, self.vx + move_x, self.vy + GRAVITY * dt) self.vy += GRAVITY * dt # 移除超过最高时长的粒子 elif self.cid is not None: cv.delete(self.cid) self.cid = None # 扩大的时间 def expand (self): return self.age <= 1.2 # 粒子是否在最高存在时长内 def alive(self): return self.age <= self.lifespan ''' 循环调用保持不停 ''' def simulate(cv): # time.sleep(0.0005) t1 = time.time() explode_points = [] wait_time = randint(10, 100) numb_explode = randint(6, 10) # 创建一个所有粒子同时扩大的二维列表 for point in range(numb_explode): objects = [] x_cordi = randint(50, 550) y_cordi = randint(50, 150) speed = uniform(0.5, 1.5) size = uniform(0.5, 3) color = choice(colors) explosion_speed = uniform(0.2, 1) total_particles = randint(10, 50) for i in range(1, total_particles): r = Particle(cv, idx=i, total=total_particles, explosion_speed=explosion_speed, x=x_cordi, y=y_cordi, vx=speed, vy=speed, color=color, size=size, lifespan=uniform(0.6, 1.75)) objects.append(r) explode_points.append(objects) total_time = .0 # 1.8s内一直扩大 while total_time < 1.8: sleep(0.01) tnew = time.time() t1, dt = tnew, tnew - t1 for point in explode_points: for item in point: item.update(dt) cv.update() total_time += dt # 循环调用 root.after(wait_time, simulate, cv) def close(*ignore): """退出程序、关闭窗口""" global root root.quit() if __name__ == '__main__': root = tk.Tk() cv = tk.Canvas(root, height=520, width=750) cv.pack() image = Image.open("./image.jpg") photo = ImageTk.PhotoImage(image) w = turtle.TurtleScreen(cv) t = turtle.RawTurtle(w) # 选一个好看的背景会让效果更惊艳！ cv.create_image(0, 0, image=photo) # root.mainloop() t.hideturtle() # 隐藏画笔 t.getscreen().tracer(5, 0) w.screensize(bg='black') # wheat小麦 t.left(90) t.up() t.backward(150) t.down() t.color('sienna') # 画樱花的躯干 Tree(60, t) # 掉落的花瓣 Petal(200, t) root.protocol("WM_DELETE_WINDOW", close) root.after(100, simulate, cv) root.mainloop()

四、飘过的雪花 

from turtle import * from random import * from math import * def tree(n,l): pd()#下笔 #阴影效果 t = cos(radians(heading()+45))/8+0.25 pencolor(t,t,t) pensize(n/3) forward(l)#画树枝 if n>0: b = random()*15+10 #右分支偏转角度 c = random()*15+10 #左分支偏转角度 d = l*(random()*0.25+0.7) #下一个分支的长度 #右转一定角度,画右分支 right(b) tree(n-1,d) #左转一定角度，画左分支 left(b+c) tree(n-1,d) #转回来 right(c) else: #画叶子 right(90) n=cos(radians(heading()-45))/4+0.5 pencolor(n,n*0.8,n*0.8) circle(3) left(90) #添加0.3倍的飘落叶子 if(random()>0.7): pu() #飘落 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) #画叶子 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()#隐藏turtle speed(0)#速度 1-10渐进，0 最快 tracer(0,0) pu()#抬笔 backward(100) left(90)#左转90度 pu()#抬笔 backward(300)#后退300 tree(12,100)#递归7层 done()

五、给你一朵玫瑰花
