Warning

Web Notebooks
To start run notebook()
from an interactive shell;
passing a directory as an argument will store files there. Also
trysage_wiki()
!
To get help on a cmd
type cmd?
in an cell
and press the Escape key.
Interactive Shell
Instead of the usual python **
you can use
^
like the rest of the world, at least from the notebook
and shell; use the old operator in scripts?
Prefacing with time
gives processor time statistics; you
can wrap a series of commands with t = cputime()
and
cputime(t)
to get the sum of time statistics;
walltime
works similarly.
The general trick for saving text representations of objects is to
open a file dscriptor and write the str
of the object to
it.
save_session
and load_session
save all
objects in the session to a .sobj
file.
