Python adds tab Auto Completion and command history functions.

1. Create a new Python environment variable configuration file:

vim ~/.pystartup# add auto-completion and a stored history file  Of commands to your python# interactive interpreter. requires python  2.0+, readline. autocomplete is# bound to the esc key by  default  (You can change it - see readline docs). ## store  the file in ~/.pystartup, and set an environment variable  to point# to it:   "Export pythonstartup=~/.pystartup"  in bash.import  atexitimport osimport readlineimport rlcompleterreadline.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

2. Set the python environment variable:

Immediate effect, restart failure: Export Pythonstartup=~/.pystartup

Permanent entry: Echo "Export Pythonstartup=~/.pystartup" >>/etc/profile

Note: The default complement is ESC.

Readline.parse_and_bind (' tab:complete ') This command is used to set tab completion.

~/.pyhistory preserves the history of the operation commands in the Python interactive interface.
