Not strange at all.  The python.org Python 2.6 (which is installed to 
/Library/Frameworks/Python.framework) is deliberately built to be 
compatible with OS X 10.3.9 through 10.6 and, as such, requires gcc-4.0 
and the 10.4u SDK.  The latter is included in the 10.6 Xcode 
distribution as a separate package but is not installed by default; to 
build a Python C extension module for that Python, you need to go back 
to the Xcode installer for Snow Leopard (or download a new one from 
Apple) and do a custom installation of that SDK.

That could be part of your problem. Macports basically ignores the
rest of the system. Setuptools depends on python, so Macports compiles
and installs its own version of Python in /opt/local. So you now have
3 different versions of Python 2.6 on your computer: /usr/bin/python
(the System python), /usr/local/bin/python (the Python.org python) and
/opt/local/Library/Frameworks/Python.Framework/Versions/2.6/bin/python.
You can use Macport's python-select package to choose which one is the
default (it symlinks one of them to /opt/local/bin/python which should
be first on your path).

Anyway, as long as you're using Macports :

sudo port install py26-mysql

that should solve most of your problems :)

Strange. Seems that the package is trying to use gcc-4.0 and the
MacOSX10.4 SDK. The default version of gcc on Snow Leopard is 4.2, and
XCode only comes with the SDKs for the previous two versions of OS X.

Getting started with python on macintosh snow leopard with mysql - need help

[dk]

I have been going round and round trying to configure python 2.6
running on osx 10.6.x to work with mySQL 5.1.44.
Python seems to work ... i have an installation of mysql 5.1.44
running and have used it in conjunction for other php/apache projects.

I want to learn python and think i need a better database then mysql
lite that installs with the web2py frame work, so my quest to connect
to mysql or postgres began.

I seem to be stuck stuck getting mySQLdb drivers installed.  I down
loaded python 2.6.5 from the python site and MySQL-python-1.2.3 from
the my sql site.
I have worked past numerous errors by i now get the errors below when
i try to compile.

 I choose python with a goal in mind the language was not
important..  Python is fantastic for input and output..  Once in a
while I get stuck and to be honest if I had a little more cash I would
be putting a small project on rent a coder that said tracker software
where the notes are defined in collums are great for practicing input
output, I can always do that myself but if there is a interest (or if
a intresting idea presents itself because small projects can be
linked) then I am game...  good luck to all of you and happy learning

Eric,

You will certainly appreciate how concise and easy Python is.
I am also relatively new to Python (started about a year ago), and I'd
rather not go back to any other language! Why would I want to torment
my not-so-quick typing fingers?? :)  I'm a self-learner. I learn by
reading, by example, and by doing.

Here is a list of suggestions. Start with simple things, grow
confident, and move on to more interesting stuff as you progress:

At the Python command line, type "import this" to see the basic ideas
behind Python development. It begins with "Beautiful is better than
ugly." - a nice thought.

1. First of all, read the publication "How to Think Like a Computer
Scientist: Learning with Python" by Allen B. Downey et al.  I have
found this little gem to be very, very useful when I first got
interested in Python and thought to myself, "how do I go about
learning this, where do I start??".  Highly recommended. I read it
from start to finish in a couple of days and started making useful
scripts right after that.  The author actually implements a simple
card game toward the end of the book, using all the knowledge from the
previous chapters.  The text is available at:
http://www.ibiblio.org/obp/thinkCSpy/

2. Play with Python from the command line first, using PyShell,
PyCrust, or any of its other siblings that come with the wxPython
package (a GUI toolkit - see #8 below).  You will find the code
completion feature and the syntax helper quite useful.

3. Tinker around with the builtin modules.  There's a lot of built-in
functionality in Python right out of the box. Try the "os" and "sys"
modules to experiment with filesystem handling. Try reading and
writing text files, as this is quite a common task with a variety of
applications. Try the "struct" module for binary file processing.  Try
the "urllib" and "urllib2" modules for loading and processing Web
pages... I could go on, but you get the idea.

4. If you have a text processing background, dip your hand in regular
expressions with the "re" module. Maybe you have a need for extracting
some statistical data from a financial report, and this might be one
way to do it.

5. If you have a mathematical background, download and install the
NumPy or SciPy package and do some wild matrix math!

6. I have recently tinkered with the Pymedia package, perhaps you want
to try it later on.  It is a nice tool for dealing with audio - for
recording, encoding, decoding, spectrum analysis, etc.  In just a few
hours, I came up with a nice voice-activated MP3 sound recorder
application.

7. If you feel brave and want to work with Windows COM client/server
stuff (assuming Windows is your platform), get the PythonWin package,
also known as "win32com" and try to read/write Excel, Word files,
etc., or whatever

8. Last but certainly not least, once you feel comfortable with basic
Python, try GUI development.  Several gui toolkits are out there.
wxPython is a good one to start with, though you may find some others
to your liking.

9. If you have previous programming experience, try taking an
application you've developed before and port it to Python.  See how
much your code base shrinks compared to its C++ or Java counterpart :)
But really, do it just to understand Python on a deeper level. Instead
of thinking in the old way, try to think in the Pythonic way.  A nice
example of this is iteration.  Where an iteration counter variable is
required in most other languages, Python inherently supports iteration
in sequence objects like lists, strings, and dictionary keys; so the
syntax is simpler in most cases.

The first example converts from seconds per 10 passes to microseconds
per pass in two steps, while the second example does it one.  The first
example is more easily understood and maintainable than the second
example.

The point is that both work equally as well unless (1) you are biased by 
a particular style or (2) you split little bitty hairs to even finer hairs.

To be strictly comparable you should have pass statements before the 
continue statements as well.  Ignoring that, clearly it's well worth 
saving that extra 390 nanoseconds each time round the loop.

Repeat after me "premature optimization is the root of all evil".

What does this accomplish:

100 * t.timeit(number=10)/10

that the following doesn't accomplish:

10 * t.timeit(number=10)

Csound is based on c but as a csound user you don't realy need to
know...  just take the instruments that are already available for
free..  Dex Tracker is just an interface to make it easier and provide
other tools..  more info on csound including manuals exc can be found

Correct, the original specification only had 3 and 5.  I gave a longer
example to illustrate how the specification might be modified.  Obviously
it is not the same specification any more.  The i%15 approach gets messy
once there are more than two numbers to check.

I don't think that's in the spirit of the original, which
would be to print 'BuzzZonk' for n=6.

I think that this is somewhat of an over-interpretation of the 
specification.

1. This doesn't act according to the specification if you add, for 
example, (2, 'Zonk'). Now 30 gives 'ZonkFizzBuzz' and not 'FizzBuzz' 
according to the specification.

2. What if additional words don't necessarily follow the pattern you 
infer? Nothing in the specification disallows adding (30, 'Whammo').

So, I would keep my original explicit testing:

def fizzbuzz(n):
   words = ((30, 'Whammo'), (15, 'FizzBuzz'),
(5, 'Fizz'), (3, 'Buzz'), (2, 'Zonk'))
   for k,v in words:
 if not k % n:
   return v
   return n

for i in xrange(1,101):
   print fizzbuzz(i)

I think I'd be more concerned about getting rid of the i%15 test.
What if a few more words get added?

def fizzbuzz(n):
words = ((3, 'Fizz'), (5, 'Buzz'), (7, 'Jazz'), (11, 'Pizzazz'))
r = ''.join(b for a,b in words if n%a == 0)
return r or str(n)

I just installed Python 2.5 a few days ago.  I like to play with
csound.

You'd be worth more if you'd used elif and omitted the continue 
statements, but for a first solution it's acceptable.

For better readability I'd have used

 if i % 5 == 0

rather than

 if not i % 5

but that's mostly a stylistic matter.

Start out with something simple and go deeper. For example, here is
one progression:

1. A simple program that counts words (wc) - read from a file,
tokenize, count
2. A variation of wc that does word frequency count (counts how many
times each word occurs) - wfc - In addition to 1, this allows you to
use a data structure to store words and search for them to update the
count. You may also sort the output.
3. A variation of wfc that reads from a file a set of noise words and
stores them in memory. As you are tokenizing, drop the noise words
from counting (or count noise words)

You could do similar things with database programming (start with
something simple and gradually increase the level of complexity or any
other area.

You can also access Python cookbook, use the examples as a starting
point and build variations. This not only allows you to read some well
written code but also understand various techniques.

Another suggestion is to get hold of a book "Software Tools" and try
to code all the examples in Python.

I found the best way to learn a language is to read some code, write
some code and keep improving it. Many improvements will suggest
themselves as you keep coding.

Hope this helps.

If you want to play around with simple graphics and writing simple
ascii files to disk then dex tracker may be a good project for you.  I
am currently playing around with generating random sounds to disk and
random rythoms.  (I also have a harder graphics problem that when I
solve will break the music program wide open).  
https://sourceforge.net/projects/dex-tracker
You would go to the (project homepage) website for dependencies
http://www.stormpages.com/edexter/csound.html (not all are required
for all sub-programs but you do want wxwindows).  It would probily be
cool to expand the idea into non-random series of numbers and I have
just started to code this particular tool.  I can upload it to my
google groups if you are intrested

Here is a protocol I have used in the past:

1. Realize there is a program you really wish you had.
2. Find out that, upon relentless googling, no
   such program exists that meets your needs exactly.
3. If 2 fails and a program exists, go back to 1.

Hi Eric, Somas1.
Try:
http://www.google.co.uk/search?source=ig&hl=en&q=beginners+programming-problems&btnG=Google+Search&meta=

Some of the sites have beginners problems meant for
another language, but in a lot of cases that doesn't
matter.

You might need to be a fair way through the Python
tutorial though before you attempt thhem so you
know the basics of Python first.

On a different tack, from:

The editor is only a part of pywin32, which is a handy package to do all

Trying to break the loop:

The above link works for me. I've tried it numerous times during this 
looping. Clicking the link pops up a security warning informing that the 
browser is going to enter "https mode". Do you get that pop-up?

When I accept the pop-up, I get a page containing a green rectangle 
"button". When I click it, I get another page in which I have to click 
download to go to the actual download page.

If this doesn't work for you there must be something wrong with your 
configuration.

We seem to be looping. I have the Python interpreter. I would like the

The above link should work. Follow the instructions in a previous post.
Note that in the last step, you have to choose a mirror for

This is the python interpreter for windows:

http://www.python.org/ftp/python/2.5/python-2.5.msi


Here you can check for editors:

http://wiki.python.org/moin/PythonEditors


Here you will get the pywin32 package (also including the Win32 API, COM
support, and Pythonwin):

http://sourceforge.net/projects/pywin32/

I am not sure if you actually read any of our posts, because there is no
404 whatsoever. On none of the posted links in the whole thread.

I don't understand your difficulties. If you've got Python installed and 
want to install the "Python for Windows extensions" aka pywin32, the 
above link is the way to go.

Clicking it gets you to a Sourceforge page, where you can click 
"download" which gets you to ap page where you can choose which version 
of pywin32 build 210 you want. Choose the exe that was built for the 
Python version (e.g. 2.5) you are using, download and run it to install 
pywin32.

My computer does, in fact, include a Python 2.2.1 installation,

Not so, but it takes a little setup. If I want to run a Python 
program named, say, "fixthis.py", I can invoke it by typing 
"fixthis.py" at the command-line prompt (if I'm running cmd.exe), 
or by clicking the icon in Windows Explorer. To make the command-
line option work, I have to have file associations set so that .py 
files open with python (and .pyw files open with pythonw, for that 
matter). I *think* this is done at install time, though I may have 
done that separately.

There is also an environment variable called "pathext", which is 
just a list of extensions the system recognizes as being 
executable in some way. if you add .py and .pyw to that list, then 
all you have to type at the command line is "fixthis" to get that 
Python program to run.

I note that I have had my Python root and Python/Scripts directory 
on my path at times. There may be some packages that require these 
things, but what I talked about in the previous two paragraphs 
doesn't require pythonpath to be set specially.

(Fiddling around) Ah! If you want to invoke the interactive python 
shell, you will probably want to add the root location to your 
path, so you can type
> python
... to invoke it, rather than
> c:\python25\python
... and something similar may be true for the Scripts 
subdirectory.

While it's true that Microsoft doesn't bundle Python with
Windows, a _lot_ of XP computers do come with Python installed.
My IBM ThinkPad came out of the box with Python installed. I've
read that a few other large PC vendors (HP/Compaq?) also ship
Python pre-installed on their machines.

However, it's not usually installed in a manner that makes it
conveniently usable by the end-user...

Re: Just Getting Started with Python on MS XP Pro

[DouhetSukd]

Wise choice + welcome to the club.

Though Python is open source and well appreciated on Linux, I think you
will find that most people in this newsgroup will be fairly courteous
about _your_ choice of platform.  Some will not know about the weird
process forking stuff on windows and helpfully suggest that 'if you
were to use a real OS...'.  But in reality Python is just as happy on
XP as on Linux and the lack of scripting/shell alternatives on XP makes
it all the more useful there.

The only real XP drawback is that Python is not bundled on Windows,
while it is included with OS X and most (all?) Linux distros.

So, giving a *.py program to another XP user means little by itself, it
needs to be either packaged in an exe (see py2exe) or you need to get
your buddy to install python on their machine.


In descending order of cheapness/usefullness.

1.  download python + work through the tutorial.  well, maybe not all
of it, but with pythonwin around, you can try out significant snippets
quickly.


2.  use any ol' text editor that _you_ are familiar with, save to file,
and python  under DOS.  later on you can always pick an editor.
i prefer eclipse + pydev, yes, even on windows.

personally, i find pythonwin _great_ to test out code interactively,
mediocre to write lots of code with and occasionally handy to debug
code in.

if you hate typing python  under DOS, then I guess you will have
to run programs from pythonwin.


3.  internet

this newsgroup is very informative.

dive into python, pretty good net resource

www.diveintopython.org



4.  books:

Learning Python, isbn 0596002815, is pretty good.

Python Programming on Win32, isbn 1565926218, is good, if a bit dated
(2000, covers COM but no .Net)

In depth Python - Python in a Nutshell, isbn 0596100469


5.  GUI stuff.

wxPython.  If, like me, you hate handcoding everything and want a VB
drag&drop clone you will have to look around for someone else's advice
- there are several such editors that do wxPython but I have never
found anything entirely to my liking.  I am sure others will chime in
with their recommendations.


6.  Database stuff.

Personally, working on MS SQL, I vouch for mxODBC - shareware, which I
used for years without paying, until I decided the guy had definitely
earned my $75.

http://www.egenix.com/files/python/eGenix-mx-Extensions.html


7.  Prepping *.py programs for distribution to users w.o. Python

py2exe - www.py2exe.org/

Best o' luck.

You mean Microsoft XP Pro?

For a beginner, the motherboard does not really matter. First of all, 
you should download Python itself:

http://www.python.org/download/

or more probably:

http://www.python.org/ftp/python/2.5/python-2.5.msi

Then you should download a good editor. There are many, listed here:

Under Windows, for a beginner, I would recommend pythonwin, but you can
