python 多张图片合并到一张

## 多张图片合并到一张（垂直）
import sys
from PIL import Image

images = [Image.open(x) for x in ['./imgs/1_page1.jpg', './imgs/1_page2.jpg', './imgs/1_page3.jpg', './imgs/1_page4.jpg', './imgs/1_page5.jpg', './imgs/1_page6.jpg', './imgs/1_page7.jpg', './imgs/1_page8.jpg', './imgs/1_page9.jpg']]
widths, heights = zip(*(i.size for i in images))

max_width = max(widths)
total_height = sum(heights)

new_im = Image.new('RGB', (max_width, total_height))

y_offset = 0
for im in images:
  new_im.paste(im, (0,y_offset))
  y_offset += im.size[1]

new_im.save('test.jpg')

有时候安装了几个版本的python，怎么指定版本安装包呢，直接找到路径，运行下面的命令。

如我得3.7安装在 C:PythonPython37python.exe

##### 更新pip
C:\Python\Python37\python.exe -m pip install pip --upgrade pip
## 安装pymysql 
 C:\Python\Python37\python.exe -m pip install pymysql    

##### 安装cryptography ---pymysql连接密码会用到

 C:\Python\Python37\python.exe -m pip install cryptography 

使用国内景象安装,中间会让你选择镜像源

安装brew

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

安装python

brew install pyton 

修改.bash_profile

vi ~/.bash_profile 

PATH="/usr/local/bin/python3/bin:${PATH}"

export PATH

修改.bashrc

sudo vi ~/.bashrc

alias python2='/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7'

alias python3='/usr/local/bin/python3'

alias python=python3

使生效

source ~/.bash_profile

source ~/.bashrc

安装pip

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py
