How to Save IPython Session

The detail of the question is described in this page How to save a Python interactive session?

There are several ways to do it.

I’ll list them below in the order of my preference.

1. %logstart

I prefer this method because it’s automatic. You don’t need to remember the saving stuff before you quit ipython. Simply type this command right after you open an Ipython session:

%logstart

This will create a uniquely named .py file and store your session.

2. %history

This is also a better option. You just type in the magic command above rigth before you quit Ipython. everything in the session will be saved to python file you named.

%history -f /tmp/history.py

3. %save my_usefull_session 10-20 23

This is the top answer to the question on stackoverflow. I don’t prefer this way becuse it’s not that easy to use. Here’s the description of this way:

For example for your use-case there is the %save magic command, you just input %save my_useful_session 10-20 23 to save input lines 10 to 20 and 23 to my_useful_session.py (to help with this, every line is prefixed by its number).

4. readline

Just another way by using python tool readline:

import readline
readline.write_history_file('/home/ahj/history')
