3、需要用到模块说明rlcompleter readline
rlcompleter:
The rlcompleter module defines a completion function suitable for the readline
module by completing valid Python identifiers and keywords.
When this module is imported on a Unix platform with the readline module available
an instance of the Completer class is automatically created and its complete() method is set as the readline completer.
readline:
The readline module defines a number of functions to facilitate completion and reading/writing of
history files from the Python interpreter.This module can be used directly or via the rlcompleter module.
Settings made usingthis module affect the behaviour of both the interpreter interactive
prompt and the prompts offered by the raw_input() and input() built-in functions.
4、具体脚本
cat .pythonrc.py
#!/usr/bin/python
# -*- coding: utf-8 -*-
#--------------------------------------------------
#Author:jimmygong
#Email:jimmygong@taomee.com
#FileName:.pythonrc.py
#Function:
#Version:1.0
#Created:2015-10-12
#--------------------------------------------------
print "success set"
try:
import readline
except ImportError:
print "Module readline not available."
else:
import rlcompleter
readline.parse_and_bind("tab: complete")
5、执行后会看到相应success set出现说明OK了
python .pythonrc.py
success set
6、将pythonrc.py脚本放到.bashrc
echo "export PYTHONSTARTUP=~/.pythonrc.py" >> .bashrc
7、生效
source .bashrc
