I *despise* programs that do that, and would cheerfully and unapologetically
take their designers, disguise them as a lettuce, and stake them out to be
nibbled to death by snails.
At the interactive prompt, I am frequently hitting Enter on a blank line,
either by accident, or deliberately to break up the calculations into groups,
or just to give myself time to think.
Blank lines should be treated as "do nothing" and simply ignored, and there
should be an explicit QUIT command.
Um, that actually follows what interactive Python does. If you type this
(I'm using <<< as the prompt as >>> confuses my newsreader's quoting
system):
<<< def fn():
<<< pass
<<< pass
At this point, you can break out by pressing the key for 'eof', or by
pressing Enter at the start of a line. Even though a blank line is legal
Python syntax.
(Most of my real interactive programs with a command line interface
programs use Escape, quit, exit, q or x to finish.
Interactive Python requires quit() or exit(), complete with parentheses.
Unless you've redefined quit and exit as something else, then you have
to crash out by other means.)
