Follow the tab to create a completion method under the python command line

Follow the tab to create a completion method under the python command line

This method is only tested on centos6 and tested on other systems.

1. Create a hidden file named. pythonstartup in the user's home directory and write the following content:

# 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)

Handle t IOError:

Pass

Atexit. register (readline. write_history_file, histfile)

Del OS, histfile, readline, rlcompleter

Note: Do not write the above format incorrectly !!!

2. Import an environment variable to the System

Here, I only import a PYTHONSTARTUP environment variable in the home directory of linux. The method is as follows:

# Echo "export PYTHONSTARTUP = ~ /. Pythonstartup ">> ~ /. Bashrc
