How Python is set using the TAB key under Linux

1. First in the home directory to create a hidden file, vi ~/.pythonstartup, the contents are as follows:

   
   

# Python startup file

Import ReadLine

Import Rlcompleter

Import atexit

Import OS

# tab Completion

Readline.parse_and_bind (' Tab:complete ')

# History File

Histfile = Os.path.join (os.environ[' HOME '), '. Pythonhistory ')

Try

Readline.read_history_file (Histfile)

Except IOError:

Pass

Atexit.register (Readline.write_history_file,histfile)

Del Os,histfile,readline,rlcompleter

2. Set the BASH environment variable:

Vi/root/.bash_profile

At the end of the document, add a sentence:

Export Pythonstartup=~/.pythonstartup

3. Restart the computer, reboot, then you can use the TAB key Auto-complete function.
