IPython has it's own history. Accessible using the %hist magic
command, the default is 1000 lines but can be changed in the ipythonrc
file.
There are many other magic commands which are very useful for
interactive development. For example there's a %log command that
enables logging of your session in a file. Another example is %save to
store parts of your history into a file and %edit to launch an
external editor to edit a bunch of commands from the history or enter
longer blocks of code. Take a look at the documentation of the magic
commands by entering %magic.
