How do you compare Python to Lisp? What specific advantages do you
think that one has over the other?
Note I'm not a Python person and I have no axes to grind here. This is
just a question for my general education.

IAor maybe it shows that Lisp is an obfuscated version of Python
hell no, lisp's syntax is much easier than python's since it's homogenous
(and certainly lisp was invented much 30 years before Python, so that's
Python uses Lisp features)

that make logic more explicit
IA backward logic,

IA and complicated constructs that run faster.
no, there are no complicted constructs -- just it's designed with 30-year
history in mind, not like "let's make another simple scripting language".

Lisp programmers are smarter and better looking. And better programmers.
Not sure if that is what you were after, though.
What specific advantages do you

Since the late 1950's Lisp has participated in the development of
modern (present day) programming practises. It has shaped and been
shaped by the minds of just not programmers, but people involved
in dealing with the larger impacts and possibilities.
Its been there, is here, and will continue to be there in the future.
Lisp is a human construct that is a force to be reckoned with. Its
construction reflects something very deep and fundamental about
computing. So, it depends on what you want.
What do you want?

heh, do you have "standard numeric packages" for everything? maybe then we'll make
standard programs for everything -- that will obsolete "slow" "custom scripts" and we'll
just use shell to select what program we want to run?
No, I was observing that, faced with a matrix multiplication problem, most
sensible Python developers would do "apt-get install python-numeric" or
equivalent. Trying to do it in pure Python would be the wrong tool for the
job. If you think that's a weakness of Python compared to Lisp, then so
be it.

I do not know much about Lisp. What I know is:
Python is a imperative, object oriented dynamic language with duck typing,
Yes, but Python also supports the functional style to some extent.
List is a declarative,
functional dynamic language
Lisp is only a functional language in that it support both functional
and imperative programming styles. Duck typing is almost identical to
latent typing in Lisp.
And, Common Lisp at least is object orientated.
-those two languages have different scopes.
Their scope is actually very similar. Learn about lisp and you will
soon discover their similarity.

interesting, that python, perl, php and ruby show very similar peformance,
while lisp and scheme implementations show large improvements -- it makes me
think that there's something "pathalogic ally scripting" in their
specifications (maybe some obligatory use of strings for method dispatch?).
"The most unusual features of the SBCL compiler (which is very similar
to the original CMUCL compiler, also known as Python) is its unusually
sophisticated understanding of the Common Lisp type system and its
unusually conservative approach to the implementation of type
declarations.
These two features reward the use of type declarations throughout
development, even when high performance is not a concern. Also, as
discussed in the chapter on performance (see Efficiency), the use of
appropriate type declarations can be very important for performance as
well." http://www.sbcl.org/manual/Handling-...dling-of-Types
If you'd read the docs of the tools you admire you might find the
answers yourself.

Whoa there, that's a pretty big logical jump there, don't you think?
Consumer choice can never be boiled down to one thing; there are so
many factors. No one knows the whole answer. I certainly don't. (If
I did, I'd be courteously turning down the Nobel Prize for Economics on
account of being so rich I really didn't need the extra pocket change.)
I have no doubt that what you say is a contributing factor, but if I
had to guess the main reason why Lisp is losing out to newbies, I'd say
it's first impressions. When newbies see Python they say, "Ok, I can
kind of follow that, it doesn't look too hard to learn." When they see
Lisp they say, "WTF IS THAT???"
It's kind of sad, in a way, that a superficiality would be so crucial.
(Not that I think outward appearance is all superficial--I think humans
have evolved and/or learned to regard as beautiful that which minimizes
effort--but it's not the whole story and not basis for a whole
judgment.)

One overlooked advantage for Lisp over Python is a better development
environment, for me that means Slime for Lisp. For Python I have
several years of experience with IDLE and the win32 Ide, and Slime is
the winner. Press a key and the function you are editing is recompiled
and loaded into memory. The crossreference and the object inspector is
very nice. How about fuzzy-complete, I only have to write de-me and
press tab, and I get define-method-combination.
Slime coupled with the paredit structured editing mode, which lets you
edit Lisp code as list structure rather than characters, is a dream.
Pythons advantages are:
Faster startup-time which makes it a good scripting language.
More platforms, there is no Common Lisp on Nokia phones.
Some clever details, like using minus to index vectors from the right.
(aref "hello" -1) gives an error on Lisp, but the character o on
Python.
Another detail I like is that you can choose how to quote strings, in
Python you can write three double-quotes to start a string that can
include anything, quotes, doublequotes and newlines.
You can use double-quote if you want to embed single-quotes "john's" or
single-quote if you want to embed double-quotes '<id="2">'.
Talking about Lisps advantages will take me too long.
/hankhero, a switcher.

it's all due to Python's humongous marketing budget, of course. just
imagine what would have happened if someone had spent that much VC money
on Lisp.

Can you give an example? I cannot imagine how homogenity always
results in easiness.
(and certainly lisp was invented much 30 years before
Python, so that's Python uses Lisp features)
I think you acknowledged that the syntax is different and not
borrowed?
[many parentheses]
that make logic more explicit
Can you give an example?
