16、json
# -*- coding:UTF-8 -*- import json import re data = {"Fence":[{"Type":2,"OrganizationId":"qqq","StationId":"ppp","Id":"ooo","Name":"ttt"}]} # json to str data_str = json.dumps(data) print(type(data_str)) print(data_str) #str to dict user_dict = json.loads(data_str) tt = user_dict['Fence'][0]['Type'] print tt

11、python读取shell指令
#output = os.popen(message['data']) #logs=output.readlines() #for line in logs: # print line return_code, logs = commands.getstatusoutput(message['data']) print logs
10、python_version_checkout
楼主是Ubuntu14.04版本，一直以来想用Python3版本，但是又不能把自带的Python2版本卸载，据说卸载之后系统会不稳定。因此一直苦于Python2和Python3无法及时切换，导致软件弄混。后来终于找到一个方法可以完美切换。切换方法如下：
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150
然后再输入：
sudo update-alternatives --config python
根据数字选择你想要的Python版本。这时，Python及其对应的pip都跟着变成默认的了。
9、virtualenv
sudo apt-get install python-pip
sudo pip install virtualenv
virtualenv -p /usr/bin/python env
source env/bin/activate
pip --version
pip install --upgrade tensorflow
pip install -r requirements.txt
8、requirements.txt
pip freeze > requirements.txt
pip install -r requirements.txt
7、python读写shell

2、Python Ctypes结构体指针处理(函数参数，函数返回)
本文演示了在python中调用C语言生成的动态库，返回结构体指针，并进行输出！
