Enable Python REPL command history and tab completion

.pystartup

# Store this file in ~/.pystartup, 
# set "export PYTHONSTARTUP=/home/user/.pystartup"
#
# Note that PYTHONSTARTUP does *not* expand "~", so you have to put in the
# full path to your home directory.

import atexit
import os
import readline
import rlcompleter

readline.parse_and_bind('tab: complete')

historyPath = os.path.expanduser("~/.pyhistory")

def save_history(historyPath=historyPath):
    import readline
    readline.write_history_file(historyPath)

if os.path.exists(historyPath):
    readline.read_history_file(historyPath)

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

Will this enable tab auto completion in repl interactive mode?
