1.生成漂亮的樱花树
参考来源
效果如下：（动态画图）
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(200, t)
w.exitonclick()
2.绝美的静态樱花树
效果图如下：

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)

#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)

8. python实现黑客帝国的代码雨
参考来源
需要安装pygame模块
1. 数字雨
效果图如下：
代码如下：
import numpy as np
import random
import pygame
FONT_PX = 15
pygame.init()
winSur = pygame.display.set_mode((500, 600))
font = pygame.font.SysFont('fangsong', 20)
bg_suface = pygame.Surface((500, 600), flags=pygame.SRCALPHA)
pygame.Surface.convert(bg_suface)
bg_suface.fill(pygame.Color(0, 0, 0, 13))
winSur.fill((0, 0, 0))
# 数字
texts = [font.render(str(i), True, (0, 255, 0)) for i in range(10)]
colums = int(500 / FONT_PX)
drops = [0 for i in range(colums)]
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit()
pygame.time.delay(33)
winSur.blit(bg_suface, (0, 0))
for i in range(len(drops)):
text = random.choice(texts)
winSur.blit(text, (i * FONT_PX, drops[i] * FONT_PX))
drops[i] += 1
if drops[i] * 10 > 600 or random.random() > 0.95:
drops[i] = 0
pygame.display.flip()
2. 字母雨
效果图如下：
代码如下：
import numpy as np
import random
import pygame
PANEL_width = 800
PANEL_highly = 800
FONT_PX = 15
pygame.init()
# 创建一个窗口
winSur = pygame.display.set_mode((PANEL_width, PANEL_highly))
font = pygame.font.SysFont('123.ttf', 22)
bg_suface = pygame.Surface((PANEL_width, PANEL_highly), flags=pygame.SRCALPHA)
pygame.Surface.convert(bg_suface)
bg_suface.fill(pygame.Color(0, 0, 0, 28))
winSur.fill((0, 0, 0))
letter = ['q', 'w', 'e', 'r', 't', 'y', 'u', 'i', 'o', 'p', 'a', 's', 'd', 'f', 'g', 'h', 'j', 'k', 'l', 'z', 'x', 'c',

texts = [
font.render(str(letter[i]), True, (0, 255, 0)) for i in range(36)
]
# 按窗口的宽度来计算可以在画板上放几列坐标并生成一个列表
column = int(PANEL_width / FONT_PX)
drops = [0 for i in range(column)]
while True:
# 从队列中获取事件
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit()
elif event.type == pygame.KEYDOWN:
chang = pygame.key.get_pressed()
if (chang[32]):
exit()
# 暂停给定的毫秒数
pygame.time.delay(30)
# 重新编辑图像
winSur.blit(bg_suface, (0, 0))
for i in range(len(drops)):
text = random.choice(texts)
# 重新编辑每个坐标点的图像
winSur.blit(text, (i * FONT_PX, drops[i] * FONT_PX))
drops[i] += 1
if drops[i] * 10 > PANEL_highly or random.random() > 0.95:
drops[i] = 0
pygame.display.flip()
9. 价值一个亿的人工智能核心代码

示例：
10. 用python在Excel画一幅像素画
效果图:
需要安装pypiwin32库和opencv库：
pip install pypiwin32
pip install opencv-python
另外需要先创建一个excel表格，尽量将格子调整为一个正方形
参考来源: 链接.
代码如下：
# 用python在excel上画一幅像素画
import win32com.client
from ctypes.wintypes import RGB
import cv2
#color_total用于存储RGB颜色
color_total=[]
#img_file为你要画的图片的名称，图片放在于.py同一个文件目录下 用绝对路径会报错(我也不知道为啥)
img_file='C:\\Users\\LQL\\Desktop\\star.jpg'
#读取图片文件
img_a=cv2.imread(img_file)
# cv2默认为BGR顺序，将顺序转为RGB
img_color = cv2.cvtColor(img_a, cv2.COLOR_BGR2RGB)
#返回height，width，以及通道数，因为不用所以省略掉
h, l, _ = img_a.shape
#打印图片总行数和列数，即竖向有多少像素，横向有多少像素
print('行数%d，列数%d' % (h, l))
#将颜色数据添加到color_total中，颜色数据方面采集完成
for i in img_color:
color_total.append(i)
#Win32#打开EXCEL
excel = win32com.client.DispatchEx('Excel.Application')
#要处理的excel文件路径#out.file是文件 绝对路径
WinBook = excel.Workbooks.Open('C:\\Users\\LQL\\Desktop\\draw.xlsx')
#要处理的excel页
WinSheet = WinBook.Worksheets('Sheet1')
#设置单元格颜色
#excel中[1,1]代表的是第一行第一列的单元格，而数组中[0][0]代表的是第一行一列
#其中color_total[x-1][y-1][0]对应的是第x行第y列图像R的值 color_total[x-1][y-1][1]代表G color_total[x-1][y-1][2]代表B
for x in range(1, h):
for y in range(1, l):
WinSheet.Cells(x, y).Interior.Color = RGB(color_total[x-1][y-1][0],color_total[x-1][y-1][1],color_total[x-1][y-1][2])
#打印正在进行描绘的像素的位置
print(x, y)
#保存
WinBook.save
#关闭
WinBook.close
11. 利用face_recognition模块给人物图片美颜
图一乐，美颜效果惨不忍睹。。
效果图：
参考来源: 链接.
需要PIL库和face_recognition库，face_recognition库貌似比较难装。。
代码如下：
# -*- coding: utf-8 -*-
from PIL import Image, ImageDraw
import face_recognition
# 将jpg文件加载到numpy数组中
image = face_recognition.load_image_file("./resource/尔康.jpg")
# 查找图像中所有面部的所有面部特征
face_landmarks_list = face_recognition.face_landmarks(image)
for face_landmarks in face_landmarks_list:
pil_image = Image.fromarray(image)
d = ImageDraw.Draw(pil_image, 'RGBA')
# 让眉毛变成了一场噩梦
d.polygon(face_landmarks['left_eyebrow'], fill=(68, 54, 39, 128))
d.polygon(face_landmarks['right_eyebrow'], fill=(68, 54, 39, 128))
d.line(face_landmarks['left_eyebrow'], fill=(68, 54, 39, 150), width=5)
d.line(face_landmarks['right_eyebrow'], fill=(68, 54, 39, 150), width=5)
# 光泽的嘴唇
d.polygon(face_landmarks['top_lip'], fill=(150, 0, 0, 128))
d.polygon(face_landmarks['bottom_lip'], fill=(150, 0, 0, 128))
d.line(face_landmarks['top_lip'], fill=(150, 0, 0, 64), width=8)
d.line(face_landmarks['bottom_lip'], fill=(150, 0, 0, 64), width=8)
# 闪耀眼睛
d.polygon(face_landmarks['left_eye'], fill=(255, 255, 255, 30))
d.polygon(face_landmarks['right_eye'], fill=(255, 255, 255, 30))
# 涂一些眼线
d.line(face_landmarks['left_eye'] + [face_landmarks['left_eye'][0]], fill=(0, 0, 0, 110), width=6)
d.line(face_landmarks['right_eye'] + [face_landmarks['right_eye'][0]], fill=(0, 0, 0, 110), width=6)
pil_image.show()
12. 将视频转化为字符视频

# 图片转字符画的原理：首先将图片转为灰度图，每个像素都只有亮度信息（用 0~255 表示）。
# 然后我们构建一个有限字符集合，其中的每一个字符都与一段亮度范围对应，
# 我们便可以根据此对应关系以及像素的亮度信息把每一个像素用对应的字符表示，这样字符画就形成了。
# 用法如下：直接拖动程序和视频（去掉双引号之类的）
# python3 video2charvideo.py video.mp4 -e
# luminance 亮度

效果如下：（动态画图）
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(200, t)
w.exitonclick()

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)

6.手绘风格的图表模块
该模块为cutecharts
最终生成HTML网页文件，打开即为所绘的图表。
示例如下：
代码如下：
from cutecharts.charts import Pie
from cutecharts.components import Page
from cutecharts.faker import Faker
def pie_base() -> Pie:
chart = Pie("Pie-基本示例")
chart.set_options(labels=Faker.choose())
chart.add_series(Faker.values())
return chart
pie_base().render()
def pie_legend_font():
chart = Pie("Pie-Legend")
chart.set_options(
labels=Faker.choose(),

8. python实现黑客帝国的代码雨
参考来源
需要安装pygame模块
1. 数字雨
效果图如下：
代码如下：
import numpy as np
import random
import pygame
FONT_PX = 15
pygame.init()
winSur = pygame.display.set_mode((500, 600))
font = pygame.font.SysFont('fangsong', 20)
bg_suface = pygame.Surface((500, 600), flags=pygame.SRCALPHA)
pygame.Surface.convert(bg_suface)
bg_suface.fill(pygame.Color(0, 0, 0, 13))
winSur.fill((0, 0, 0))
# 数字
texts = [font.render(str(i), True, (0, 255, 0)) for i in range(10)]
colums = int(500 / FONT_PX)
drops = [0 for i in range(colums)]
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit()
pygame.time.delay(33)
winSur.blit(bg_suface, (0, 0))
for i in range(len(drops)):
text = random.choice(texts)
winSur.blit(text, (i * FONT_PX, drops[i] * FONT_PX))
drops[i] += 1
if drops[i] * 10 > 600 or random.random() > 0.95:
drops[i] = 0
pygame.display.flip()
2. 字母雨
效果图如下：
代码如下：
import numpy as np
import random
import pygame
PANEL_width = 800
PANEL_highly = 800
FONT_PX = 15
pygame.init()
# 创建一个窗口
winSur = pygame.display.set_mode((PANEL_width, PANEL_highly))
font = pygame.font.SysFont('123.ttf', 22)
bg_suface = pygame.Surface((PANEL_width, PANEL_highly), flags=pygame.SRCALPHA)
pygame.Surface.convert(bg_suface)
bg_suface.fill(pygame.Color(0, 0, 0, 28))
winSur.fill((0, 0, 0))
letter = ['q', 'w', 'e', 'r', 't', 'y', 'u', 'i', 'o', 'p', 'a', 's', 'd', 'f', 'g', 'h', 'j', 'k', 'l', 'z', 'x', 'c',
'v', 'b', 'n', 'm', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
texts = [
font.render(str(letter[i]), True, (0, 255, 0)) for i in range(36)
]
# 按窗口的宽度来计算可以在画板上放几列坐标并生成一个列表
column = int(PANEL_width / FONT_PX)
drops = [0 for i in range(column)]
while True:
# 从队列中获取事件
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit()
elif event.type == pygame.KEYDOWN:
chang = pygame.key.get_pressed()
if (chang[32]):
exit()
# 暂停给定的毫秒数
pygame.time.delay(30)
# 重新编辑图像
winSur.blit(bg_suface, (0, 0))
for i in range(len(drops)):
text = random.choice(texts)
# 重新编辑每个坐标点的图像
winSur.blit(text, (i * FONT_PX, drops[i] * FONT_PX))
drops[i] += 1
if drops[i] * 10 > PANEL_highly or random.random() > 0.95:
drops[i] = 0
pygame.display.flip()
9. 价值一个亿的人工智能核心代码
while True:
print(input('').replace('吗', '').replace('？', '!'))
示例：
10. 用python在Excel画一幅像素画
效果图:
需要安装pypiwin32库和opencv库：
pip install pypiwin32
pip install opencv-python
另外需要先创建一个excel表格，尽量将格子调整为一个正方形
参考来源: 链接.
代码如下：
# 用python在excel上画一幅像素画
import win32com.client
from ctypes.wintypes import RGB
import cv2
#color_total用于存储RGB颜色
color_total=[]
#img_file为你要画的图片的名称，图片放在于.py同一个文件目录下 用绝对路径会报错(我也不知道为啥)
img_file='C:\\Users\\LQL\\Desktop\\star.jpg'
#读取图片文件
img_a=cv2.imread(img_file)
# cv2默认为BGR顺序，将顺序转为RGB
img_color = cv2.cvtColor(img_a, cv2.COLOR_BGR2RGB)
#返回height，width，以及通道数，因为不用所以省略掉
h, l, _ = img_a.shape
#打印图片总行数和列数，即竖向有多少像素，横向有多少像素
print('行数%d，列数%d' % (h, l))
#将颜色数据添加到color_total中，颜色数据方面采集完成
for i in img_color:
color_total.append(i)
#Win32#打开EXCEL
excel = win32com.client.DispatchEx('Excel.Application')
#要处理的excel文件路径#out.file是文件 绝对路径
WinBook = excel.Workbooks.Open('C:\\Users\\LQL\\Desktop\\draw.xlsx')
#要处理的excel页
WinSheet = WinBook.Worksheets('Sheet1')
#设置单元格颜色
#excel中[1,1]代表的是第一行第一列的单元格，而数组中[0][0]代表的是第一行一列
#其中color_total[x-1][y-1][0]对应的是第x行第y列图像R的值 color_total[x-1][y-1][1]代表G color_total[x-1][y-1][2]代表B
for x in range(1, h):
for y in range(1, l):
WinSheet.Cells(x, y).Interior.Color = RGB(color_total[x-1][y-1][0],color_total[x-1][y-1][1],color_total[x-1][y-1][2])
#打印正在进行描绘的像素的位置
print(x, y)
#保存
WinBook.save
#关闭
WinBook.close
11. 利用face_recognition模块给人物图片美颜
图一乐，美颜效果惨不忍睹。。
效果图：
参考来源: 链接.
需要PIL库和face_recognition库，face_recognition库貌似比较难装。。
代码如下：
# -*- coding: utf-8 -*-
from PIL import Image, ImageDraw
import face_recognition
# 将jpg文件加载到numpy数组中
image = face_recognition.load_image_file("./resource/尔康.jpg")
# 查找图像中所有面部的所有面部特征
face_landmarks_list = face_recognition.face_landmarks(image)
for face_landmarks in face_landmarks_list:
pil_image = Image.fromarray(image)
d = ImageDraw.Draw(pil_image, 'RGBA')
# 让眉毛变成了一场噩梦
d.polygon(face_landmarks['left_eyebrow'], fill=(68, 54, 39, 128))
d.polygon(face_landmarks['right_eyebrow'], fill=(68, 54, 39, 128))
d.line(face_landmarks['left_eyebrow'], fill=(68, 54, 39, 150), width=5)
d.line(face_landmarks['right_eyebrow'], fill=(68, 54, 39, 150), width=5)
# 光泽的嘴唇
d.polygon(face_landmarks['top_lip'], fill=(150, 0, 0, 128))

12. 将视频转化为字符视频
需要在命令行下运行，并且视频转化需要一定时间。。
效果如下：

# 图片转字符画的原理：首先将图片转为灰度图，每个像素都只有亮度信息（用 0~255 表示）。
# 然后我们构建一个有限字符集合，其中的每一个字符都与一段亮度范围对应，
# 我们便可以根据此对应关系以及像素的亮度信息把每一个像素用对应的字符表示，这样字符画就形成了。
# 用法如下：直接拖动程序和视频（去掉双引号之类的）
# python3 video2charvideo.py video.mp4 -e
# luminance 亮度
