	Perhaps you should use the -c option of the python
	interpreter? Something like:

	$ python -c 'print "a"'

	But I'd like to use your question as a starting point for a
	question of mine.

	Unfortunately, I have the impression that writing one-liners
	in Python isn't as easy as writing one-liners in Perl (for me
	at least -- I am still a newbie in Python).  The reason for my
	impression is that there aren't block delimiters like C's or
	Perl's "{" and "}" available in Python.

	As a result, I don't know how one would convert to a
	one-liner, say, something along the lines of the following
	code:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
	while (cond1 and cond2):
	    # do something

	# now, which condition failed? cond1 or cond2?
	if (cond1):
	    # cond2 failed and cond2 didn't
        else:
            # cond1 failed
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

	So, while converting this to a one-liner, how does one
	indicate to that the if is not contained within the while
	loop?

	Any help with this issue would be more than welcome.


	Thanks in advance, Roger...
