Set the python command line interaction program to auto-complete and python to complete

1. 1. Create a 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. 2. Set Python environment variables:

3. Takes effect immediately. Restart failed: export PYTHONSTARTUP = ~ /. Pystartup

4. Valid permanently for the current user: echo "export PYTHONSTARTUP = ~ /. Pystartup ">> ~ /. Bash_profile
