Ahem. Sorry for any confusion caused. The OP was asking about the
situation on Windows, and I was responding in that context. The
Ctrl-Z thing is what *exits* the interpreter on Windows (a la Ctrl-D
on Linux).

In short - on Windows, within one cmd shell you can open and exit
the interpreter as many times as you like and the Python command
history will be retained via the cmd shell's history mechanism,
and kept distinct from the history of other things you may type
into the cmd shell.

If you exit the cmd shell then that history is lost, and I'm not
aware of any mechanism for retaining it.

All this may or may not be of any use to the OP. I was responding
to this comment by Steven:

"The default interactive interpreter for Python doesn't have persistent
history, so if you exit the interpreter and restart it, your commands
are gone."
