For programs, I usually have two shells: one interactive shell where
I test fragments (usually to find out how some library call needs to
be spelled); and another shell to run the program in.
For libraries, I typically reload the library module in a single
interactive shell.
I often want to do sequences of actions. I first type them one
by one, e.g.
py> import httplib
py> httplib=httplib.HTTP("localhost")
py> import httplib
py> h=httplib.HTTP("localhost")
py> h.connect()
py>
Then, I get tired of fetching all the lines from the history
again and again, and rephrase it (through cut-n-paste) as
py> import httplib;h=httplib.HTTP("localhost");h.connect()
Then I only need to fetch a single line from the history
to redo all the initialization.
I set-up readline so the history survives the end of
the interpreter. I quit the interpreter, restart it,
and immediately have the last command I typed available, see
my attached .pythonrc.
