Python command line completion

Python command line completion

As you know, when you enter a command in the command line interface, you can use the TAB key to fill in the command, which is easy to set up without wasting a long time on the input command. Recently started contacting Python and found that using the TAB key under the Python command line is not a complete command. Can we set the pattern to complete the command line? The answer is yes.

We can import modules under the Python command line

Import ReadLine, Rlcompleter; Readline.parse_and_bind ("Tab:complete")

With this setting, we can use the TAB key to complete the completion. But the downside to this approach is that you shut down the interface, and when you re-enter the Python interface, you have to re-enter the command, which is a hassle.

So, we can also write a configuration file that will permanently write this parameter

Create a file: ~/.pythonstartup.py

Vim ~/.pythonstartup.pyimport ReadLine, Rlcompleter; Readline.parse_and_bind ("Tab:complete")

Add an environment variable inside the ~/.BASHRC

Vim ~/.bashrcexport pythonstartup=~/.pythonstartup.py

Finally again source ~/.BASHRC

In this way, each time you start Python, you can automatically complete the command
