Backporting from Python 2.3 to Python
2.2
Backporting from Python 2.3 to Python
2.2
06/08/2004 11:18 PMWe have a home-grown templating system at work, which I
intend to dedicate an entry to some time in the future. We originally
wrote it in Python 2.2, but upgraded to Python 2.3 a while ago and
have since been evolving our code in that environment. Today I found a
need to load the most recent version of our templating system on to a
small, long neglected application that had been running the original
version ever since it had enough features to be usable.
Unfortunately, this application was running on a server
that only had Python 2.2. Installing Python 2.3 would have been
somewhat more painful here than on other servers we run for reasons I
won't go in to, so I decided to have a go at getting our current code
to run under the older Python version.
In the end, I only had to make three minor changes, all at
the top of the file in question.
I added from __future__ import
generators as the very first line of the file. We use
generators (with the yield statement) in a
few places - this feature was only properly added in Python 2.3, but
was made available in Python 2.2 as a "future enhancement" through the
aforementioned obscure import.
I added True, False = 1,
0 on the next line down. Surprisingly, Python 2.2 had no
support for a boolean type and instead used a test for non-zero
instead. The above line defines constants that behave enough like
Python 2.3's True and False to avoid any problems.
I defined an enumerate
function, which was introduced for real in Python 2.3. Here's the code
I used:
def enumerate(obj):
for i, item in zip(range(len(obj)), obj):
yield i, item
All in all it only took around ten minutes to put the
above together, after which the script worked just fine. It was
interesting to see how our code had grown to rely on Python 2.3
features without us realising it.

PHP Everywhere: Python vs. PHP?
PHP Everywhere: Python vs. PHP?

Everywhere today:
Another look at PHP and Python
Another look at PHP and Python
02/10/2004 02:46 AMPostscript: Some people have got the impression from this article
that I am moving away from PHP. That is far from the truth. I will
continue to use PHP extensively today, tomorrow and for the forseeable
future.
I find Python harder than PHP.
It could be because we are programming multi-threaded networked
servers in Python, and that
could be inherently harder than coding dynamic web-sites.
Another reason could be lack of familiarity with
Python. For example, I couldn't find the equivalent of htmlspecialchars
and other functions, so i had to roll my own.
Despite all these issues, we are continuing to develop this in
Python because (AFAIK) PHP does not have stable networking frameworks.
So what do I like about Python?
- Neat Syntax
The use of indentation for compound statements discourages deep
nesting, and thus more modular code.
- More Safety Checks
In PHP, when you search using a regular expression, an associative
array is returned.
In Python, a typed object, "match" is returned when a regular
expression search is performed,
and not a generic dictionary. You cannot perform arithmetic on
strings, an explicit cast is required; neither
can you concatenate numbers with strings, explicit typecasts are
needed.
- Supports Multi-Threaded Apps
There exists a global lock in Python that prevents multi-threading
from working effectively on multiple processors - nevertheless Python
has reasonable thread support and allows me to develop reasonably
responsive servers.
- Python's Compiler is Standard
Python has a standard compiler and byte-code format. There is no
such standard in the PHP world, and
most ISP's don't support Zend or Turck MMCache encoded PHP. Better
still, a debugger is included in the package too.
- Python Fully Supports Unicode
Python 2.0 and later has full support for unicode. For example to
convert big5 to unicode is the simple:
unicode_str = unicode(tw_chinese_string, 'big5')
In contrast, see how complicated it is to perform
double-byte to unicode conversions in PHP (see User Notes).
The only issue i had with the unicode support is that it doesn't
come with a complete set of double-byte decoders (eg. big5, gb). After
a 20 minute google search, i found this set of python cjk decoders.
And what I dislike about Python
- Python Is Not Rapid Enough?
I think that PHP is a better tool for rapid application
development, especially for web-sites. Minor type issues are handled
for you transparently in PHP. In Python, once a variable is set,
stricter type-checking is performed on most operations.
So you can argue that Python is safer. But PHP coding is definitely
more rapid.
Another thing i dislike is that Python's import/load facility does
not check .py file modification dates. If i modify a .py file,
Python's run-time environment will not recompile it until i restart
Python, or perform a reload manually from the command-line
interpreter.
- Database Access
Python does not have official database drivers, and you have to
select and download these drivers
yourself. It's easy to get it wrong. For example, only after coding
the adodb_odbc module using PythonWin
odbc extension did i
realize how awful PythonWin odbc was. I then found the mxODBC
extension - unfortunately the mxODBC requires commercial
licensing ($75 per CPU).
- Python is Not That Popular
Popularity is relative. There are lots of Python programmers - but
there are perhaps 3 times more PHP programmers than Python ones. In
Malaysia, the ratio of PHP to Python programmers is probably much
worse (10:1?). And there are many training centers offering PHP
courses. AFAIK, there are no centers in Malaysia offering Python
training.
A quick search in monster.com reveals the following (numbers might
change over time):

include "adodb.inc.php";
$conn = NewADOConnection('mysql');
$conn->Connect('server','user','pwd','db');
$rs = $conn->Execute('select * from tab);
while (!$rs->EOF) {
print_r($rs->fields);
$rs->MoveNext();
}
$rs->Close();
$conn->Close();
|
import adodb_mysql;
conn = adodb_mysql.adodb_mysql()
conn.Connect('server','user','pwd','db')
cursor = conn.Execute('select * from tab)
while not cursor.EOF:
print cursor.fields
cursor.MoveNext()
cursor.Close()
conn.Close()
|
It also supports the iterator protocol:
cursor = conn.Execute('select * from table')
for row in cursor:
print row
Python does have the DB API, but it's similar to ODBC in that it
provides a very minimal layer, without abstracting SELECT ... LIMIT,
LOBs, string quoting, etc.
Download zip.
I will try to post a comparison between developing in Python and PHP
when I have more time.

Python vs Parrot
Python vs Parrot
12/17/2004 06:34 PMIn many ways, it seems like Python and Parrot are from different
planets. In Python, the general approach seems to be to reduce
everything possible to a canonical form as early as possible, and then
deal with everything consistently. In Parrot, the general approach
seems
to be to leave everything in its original form as long as possible,
and
then deal with everything separately. ...
