preserve history in the interactive python

[Nikhil]

Hi,

I am using python -i, and I find it hard typing/pasting the commands
from the previous interactive shell. Basically, is there anyway that I
can preserve the history in the shell?
I guess but not sure there should be something like ~/.pyrc for
configuring such but can someone please let me know what is the
effective environment variable to preserve the history?

Thanks,
Nikhil

>>there should be something like ~/.pyrc

please read it as something in a file pointed by PYTHONSTARTUP
environment variable. I am mostly here interested in saving the python
shell's history automatically.

I figured it out. This below thing works fine for me.
BTW, I got it from http://docs.python.org/tut/node15.html. A little
search would not hurt ;-)


$ echo $PYTHONSTARTUP
/u/me/.pyrc
$ cat .pyrc
import sys
import atexit
import os
import readline
import rlcompleter

myprompt='$ '
myhistoryfile="/u/me/.pyhistory"

#set the prompt
sys.ps1=mypromp t

#save the history
historyPath = os.path.expandu ser(myhistoryfi le)

def save_history(hi storyPath=histo ryPath):
import readline
readline.write_ history_file(hi storyPath)

if os.path.exists( historyPath):
readline.read_h istory_file(his toryPath)

atexit.register (save_history)
del os, atexit, readline, rlcompleter, save_history, historyPath

Or you could use IPython (http://ipython.scipy.org/), "an Enhanced
Python Shell".
