Then I had reason to learn Python, or actually Jython, or a tool that used Jython for scripting. I went to the O'Reilly, and it started with using Python as a shell. (Or, Jython. Or ... whatever.) Then the oddest thing happened.
I used the Python shell as a calculator.
More than once.
That wasn't the push that made me consider
re.pl. It was this helpful .rc file from recent blog commenter xenoterracide.
I don't use it often yet. I keep
test.plwith the current test code at the top and most everything but the module declarations commented out, just for this purpose. And, as a purely aesthetic issue, I want to munge the way the prompt looks. But I'm sure I will use it.
