设置python中TAB键自动补全方法

设置python中TAB键自动补全方法python

linux服务器上:###########################################################################linux

1、建立自动补全脚本以下:shell

vi /tmp/python/tab.pywindows

#!/usr/bin/python服务器

# python tab file  app

import syside

import readlinespa

import rlcompleterorm

import atexitip

import os

# tab completion

readline.parse_and_bind('tab: complete')

# history file

histfile = os.path.join(os.environ['HOME'], '.pythonhistory')

try:

    readline.read_history_file(histfile)

except IOError:

    pass

atexit.register(readline.write_history_file, histfile)  

del os, histfile, readline, rlcompleter

2、导入上面建立的模块

-----------------方法一:

#python

>>>import sys

>>>sys.path.append('/tmp/python/')

>>>import tab

----------------方法二:

cp  /tmp/python/tab.py /usr/lib/python2.6/site-packages

#python

>>>import tab

#至此即可利用TAB补全了

ipython也有tab自动补全功能,安装方法以下:

tar -zxvf ipython-0.12.tar.gz 

cd ipython-0.12

python setup.py install


ipython


#注:在ipython中使用!加命令九如同在shell中同样,如!init 0


windows服务器上:###########################################################################

一、安装Python后将C:\Python27和C:\Python27\Scripts加入系统环境变量path中

二、安装pyreadline,方法以下:

pip.exe install pyreadline 或者easy_install pyreadline

三、在C:\Python27\Lib\site-packages新建tab.py,内容以下

#!/usr/bin/python

# python tab file  

import sys

import readline

import rlcompleter

import atexit

import os

# tab completion

readline.parse_and_bind('tab: complete')

# history file

histfile = os.path.join(os.environ['HOMEPATH'], '.pythonhistory')

try:

    readline.read_history_file(histfile)

except IOError:

    pass

atexit.register(readline.write_history_file, histfile)  

del os, histfile, readline, rlcompleter

在一个系统中共存Python二、python3的时候,pip、pip二、pip3使用的时候会报错:

c:\Python36\Scripts>pip3
Fatal error in launcher: Unable to create process using '"'

解决方法:

python3:

python3 -m pip install --upgrade pip

python2:

python2 -m pip install --upgrade pip

注意:python2, python3共存时,将python安装目录下的python.exe改为对应的python2.exe,python3.exe

python3 -m pip pyreadline 或者python3 -m easy_install pyreadline
