用python给朋友做生日快乐祝福

画蛋糕

主要使用python的turtle库进行绘制
speed控制画笔的速度，大小在（0， 10），0是最快的
代码如下

import turtle as t
import math as m
import random as r

def drawX(a, i):
    angle = m.radians(i)
    return a * m.cos(angle)

def drawY(b, i):
    angle = m.radians(i)
    return b * m.sin(angle)

t.bgcolor("#d3dae8")
t.setup(width=900, height=600, startx=0, starty=0)
t.title("姓名，祝你生日快乐！")

python第三方库的导入

导入第三方库的时候，可以在命令行输入pip install (要导入的库的名字)，如
pip install pygame
pip install pyinstaller

用pyinstaller打包成exe文件

写完的python想给别人用，但是别人电脑上又没有环境，怎么运行？

这时候，pyinstaller就开始表演了。Python生成可执行文件(exe )，即打包
先安装pyinstaller包

pip install pyinstaller

在终端上输入

 py -3.10 -m PyInstaller -F '.\happy birthday.py'

或者

python -m PyInstaller -v

具体的"-m", "-v"含义如下图

这是打包后的exe文件样子，把这个转发给好朋友，即使没有python的环境也可以运行了
