7.17.1 Example

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
