I've also had this annoying blank line problem a lot before. Don't know why it can't be fixed in the Python interpreter / compiler?? I mean, it's a simple thing.


These days I don't leave any blank lines unless it's really the end of a block.

In defense of Python I would like to site NVDA. High performance areas are coded in C++ but where a more dynamic approach is required it's all Python. NVDA performs really well in my opinion, and it just gets better each new release.

Sina I have told Tylor that I will not respond to anything he posts so this
is pushing it to answer your post here but yes I have went as far as python
can go and it broke.  I don't like mentioning it because python is a great
language for many things. but yes our rather large python project which is
pretty much an accessible front end for Linux, word processor, web browser,
media player, radio tuner, book reader, twitter application, rss reader,
email, all wrote in python Just got to the point where python was slowing
things down even know the major lifting was done with c++ modules.  So while
we could crank out more and more apps they got slower and slower.  So yes we
took python where we thought it could go and it broke.  I already mentioned
once where a block of code looked right but was not for example something
like this

if expression :
    do something

   do something
   do something
   do something

Now that looks right if you intended the whole 4 lines to be in the if
statement but if you were blocking the three lines and they took the
indentation which some editors do you might not notice you had it at the
same level as a blind coder.  This happened actually to a sighted coder and
the code was in for a long time and I mean years before it was finally
found.  Luckily it was not that important a bit of code but it took a blind
guy and some pain staking looking to find the problem.  Granted this don't
happen a lot but it does happen more than it does in languages that use true
blocks of code.

As for the typing of the language don't get me started you don't know how
many times I  and others have pushed stuff from the web into a sqlite3 data
base and taken it out and got nothing like we expected because of unicode
and Ascii.  I still like python for quick stuff but give me a typed language
any day.

I have, as has Ken more than me, and both of us have experienced the
complete misery that is the lack of proper typing in
multiperson development teams.

Out of curiosity, have you? been in a multiple person development team, I
mean, so that you can back up how well Python works?

Take care,
Sina

Have you coded in python frequently enough to be able to back up the
statement that coding in Python dies after big projects? I've added to
some python projects and you can still code just as fast.

Best trained profesionals in this area choose the platform and technology

So If I have a project that I can do better and quick in python than I
will
choose that langgage.
If options are better in java I will choose it.
Depends very much on the project requirements.

I personally find arguments about programming languages much analogous
to those seen in politics.  Both sides have great points but tend to
drive one another towards opposite extremes.  Some camps are die hard
dynamic language practitioners while others stick to strongly typed
code.

I will say that strongly typed languages have kind of won the battle
historically.  Most of the industry writes in C-styled languages like
C/C++, java, etc.  Lisp, still beloved by many, kind of lost.  Python,
as many have shown, works wonderfully and frees up coders to actually
code, is still largely a wrapper on C.  For those who want absolute
performance, it's considered still an extra level of indirection
that's not worth the productivity gain.

I love python and its free-form style and the amount of progress you
can make using it.  Python excels at the rinse and repeat (compile,
run, fix) style of coding.  The few seconds you need to compile a
C-styled language and run, you're already fixing the bug in python.
You're not babied into writing object-oriented code ala java, but can
independently mix in functional aspects if you wish.  You can just as
easily go OO if you want as well.

Programming is certainly a matter of preference in most situations. I
would probably give up if the only option were php, since I really
hate that language (no offense to anyone). Java is easy enough, but I
agree that it feels bulky at times. I like Python's ease of use and
readability, plus you can create executables with it, something that
is difficult in java. Some people don't like that python is loosely
typed, but I prefer saying:
name=raw_input("Enter your name: ")
to, if memory serves:
name=new String();
in=new InputReader();
name=in.readLine();
or something along those lines.

I've used both. I really like python because it comes on most *nix

Java is nice enough, but it feels big bulky and clunky to me. That and
they seem to have some serious naming convention issues. Sometimes
things are capitalized, sometimes they're not--.net makes more sense.

Why
is that?Personally i much prefer Java. Its syntx makes a lot more
sense
and it is just as powerful, if not more. A command-line build system
like ant can take most of the hassle out of working with Java
classes.
personally, I prefer this to Eclipse.

BrailleBlaster is written in Java. I am using openjdk-1.6, Eclipse
SWT
and Apache Ant.
