在使用python的时候有时候总是忘记很多代码，这个是作为程序袁最头疼的事情，本人也是刚刚接触python，这几天也是用到这块，所以记录下来，已被需要时能够找到。
我的系统是：
1 w@w:~$ uname -a
2 Linux w 4.2.0-16-generic
#
19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
先看看自己的python安装路径，如果不知道的话可以根据下面的方法查看以下：
1 w@w:~$ python
2 Python 2.7.10 (default, Oct 14 2015, 16:09:02)
3 [GCC 5.2.1 20151010] on linux2
4 Type

for more information.
5 >>>
import sys
6 >>> sys.path
7 [
'',
'
/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/ubuntu-sso-client
']
既然找到了python的安装路径，把下面的代码传进去
1
#
!/usr/bin/python
2
#
python startup file
3
import sys
4
import readline
5
import rlcompleter
6
import atexit
7
import os
8
#
tab completion
9
readline.parse_and_bind(
'
tab: complete
')
10
#
history file
11
histfile = os.path.join(os.environ[
'
HOME
'],
'
.pythonhistory
')
12
try:
13 readline.read_history_file(histfile)
14
except IOError:
15
pass
16 atexit.register(readline.write_history_file, histfile)
17
del os, histfile, readline, rlcompleter
所传路径以及文件名称可以随意，但是在调用的时候要一致。但是文件必须传到python路径下：
1 w@w:/usr/lib/python2.7/dist-packages$ vi tab.py
2
#
!/usr/bin/python
3
#
python startup file
4
import sys
5
import readline
6
import rlcompleter
7
import atexit
8
import os
9
#
tab completion
10
readline.parse_and_bind(
'
tab: complete
')
11
#
history file
12
histfile = os.path.join(os.environ[
'
HOME
'],
'
.pythonhistory
')
13
try:
14 readline.read_history_file(histfile)
15
except IOError:
16
pass
17 atexit.register(readline.write_history_file, histfile)
18
del os, histfile, readline, rlcompleter
我把文件传到/usr/lib/python2.7/dist-packages目录下，并且用tab.py命名。
1 w@w:~$ vi .bashrc
2
#
for python
3
export PYTHONSTARTUP=/usr/lib/python2.7/dist-packages/tab.py
4
#
上面的路径和文件名必须和上面的保持一致。
5
w@w:~$ source .bashrc
#
启用上面的环境
