```python
url = 'http://{0}:{1}/{2}'.format('0.0.0.0', 2375, 'xxx')
url = 'http://{ip}:{port}/{uri}'.format(ip='0.0.0.0', port=2375, uri='xxx')
url = 'http://%s:%d/%s' % ('0.0.0.0', 2375, 'xxx')
```
## Windows Python 依赖库[ **PythonLibs**](http://www.lfd.uci.edu/~gohlke/pythonlibs/)
* 1.找到对应的 `whl` 包下载
* 2.直接`pip install *.whl` 或者修改`.whl`文件为`.zip`文件，解压缩文件的`Python文件夹`复制到--`python`安装目录下的`Lib`--目录下

## Python2.7环境变量
> 假如`sys.path`不对,则使用Python终端 ` sys.path = [...] `重新设置即可.
> 默认环境配置如下：
```shell
root@node-40:~# python
Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7']
>>>
```
```shell
# /etc/profile
export PYTHONPATH=/usr/lib/python2.7:/usr/lib/python2.7/plat-x86_64-linux-gnu:/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/lib-old:/usr/lib/python2.7/lib-dynload:/usr/local/lib/python2.7/dist-packages:/usr/lib/python2.7/dist-packages:/usr/lib/python2.7/dist-packages/PILcompat:/usr/lib/python2.7/dist-packages/gtk-2.0:/usr/lib/pymodules/python2.7
export PATH=$PATH:$PYTHONPATH
```
## Windows环境`Python2.7`与`Python3.x` 共同使用
* Python2.7 : `$ py -2`
* Python3.x : `$ py -3`
* Python2.7 pip : `$ py -2 -m pip xxx`
* Python3.x pip : `$ pip3 xxx`
## pycharm
> settings
* enable Code compatibility inspection: `settings` --> `code compatibility inspection`
## Python内置工具
* 下载服务器：
* Python2.x
* `$ python -m SimpleHttpServer` 默认端口8000
* `$ py -2 -m SimpleHTTPServer` 默认端口8000
* `$ py -2 -m SimpleHTTPServer 9090` 指定端口9090
* 使用代码：
```python
import SimpleHTTPServer
SimpleHTTPServer.test()
```
* Python3.x
* `$ python -m http.server`
* `$ py -3 -m http.server`
* Json格式化：`$ curl http://localhost:8080/get | python -m json.tool`
* 执行Python代码：`$ python -c "print 'hello world!'"`
* 解压zip包：
* 创建zip包：`$ python -m zipfile -c tom.zip tom.txt`
* 解压zip包：`$ python -m zipfile -e tom.zip .`
* 查看zip包：`$ python -m zipfile -l tom.zip`
* 文件处理：
```python
import shutil
shutil.copy('C:\Users\Administrator\Desktop\ctools2.rar','q.rar')
```
