Python 中的tab补全
用Python时候没有TAB补全，挺痛苦的，以下是添加方法1.准备一个Python脚本 cat > tab.py <<EOF
#!/usr/local/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['HOME'], '.pythonhistory')
try:
readline.read_history_file(histfile)
except IOError:
pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter
EOF
2.查看Python默认的模块存放位置
# python
Python 2.7.6 (default, Sep 17 2017, 04:41:33)
on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']
3.拷贝到目录下
cp tab.py /usr/local/lib/python2.7
4.现在可以用了
# cp tab.py /usr/local/lib/python2.7
# python
Python 2.7.6 (default, Sep 17 2017, 04:41:33)
