The following example demonstrates how to use the readline module's history reading and writing functions to automatically load and save a history file named .pyhist from the user's home directory. The code below would normally be executed automatically during interactive sessions from the user's $PYTHONSTARTUP file.
import os histfile = os.path.join(os.environ["HOME"], ".pyhist") try: readline.read_history_file(histfile) except IOError: pass import atexit atexit.register(readline.write_history_file, histfile) del os, histfile
