How to Set Up IPython’s Default Configuration?

Estimated read time 2 min read

IPython is a powerful interactive shell for Python that offers a variety of configuration options to customize your working environment. Here’s how you can set up IPython’s default configuration:

  1. Open a terminal or command prompt.
  2. Launch IPython by running the following command:
ipython
  1. Once IPython starts, you can access its configuration system by typing:
%config

This will display a list of available configuration options.

  1. To set a default configuration value, you can use the %config command followed by the configuration option and its value. For example, to set the default editor for IPython to Nano, you can run the following command:
%config InteractiveShell.editor='nano'
  1. To make your default configuration settings permanent, you can save them to a configuration file. IPython uses the ipython_config.py file located in your IPython profile directory to store configuration settings. You can find your profile directory by running the following command within IPython:
%env IPYTHONDIR

This will display the path to your IPython profile directory.

  1. To add a configuration option to your configuration file, open the ipython_config.py file with a text editor and add the configuration option and its value to the file. For example, to set the default editor to Nano, add the following line to the file:
c.InteractiveShell.editor = 'nano'
  1. Save the ipython_config.py file and exit your text editor.
  2. Restart IPython for the changes to take effect.

These are the basic steps to set up IPython’s default configuration. You can explore the IPython documentation for more advanced configuration options and use cases.
