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：

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']
>>> 
# /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

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：
      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：

    import shutil

shutil.copy('C:\Users\Administrator\Desktop\ctools2.rar','q.rar')
