Re: SOAPpy.Types.faultType: Cannot use object of type stdClass as array
Hi Chris!
The example from the website is buggy because the WSDL urls are not
correct...
$WSDL_AUTH = 'https://kasapi.kasserver.com/soap/wsdl/KasAuth.wsdl'
$WSDL_API ='https://kasapi.kasserver.com/soap/wsdl/KasApi.wsdl'
which I had replaced so far.
then you will see the results, even if the login and pass do not match.
I think for many python developers it might be really interesting to
know, WHAT A PHP ARRAY is in python in a SOAP environment.

Sorry my typo in the output here is the correct output that i need :
[('John Konon', 'Ministry of moon Walks', '4567882', '27-Feb'),
( 'Stacy Kisha', 'Ministry of Man Power', '1234567', 17-Jan')]
the difference is that i need a [(row two), (row three), (row fouth)] . I do
not want to display row one which is ['Name', ' Address', 'Telephone',
'Birthday']

Is this what you need?
but this allocates memory and will be a trouble when you have a big table :P
Note that I assume your csv file content are comma seperated.

I had to add a delimiter= to accomodate the fact that your data is tab-
separated.
The first two code sections address the dropping of row-zero.
The third section changes the square brackets to parens, if that's what
you really wanted.
The fourth section goes all around the barn to get the linefeeds in the
right place. There's still one extra space on the first line, but
that's an exercise for the reader.
run with CPython 2.7.3
import csv
original = [
"Name AddressTelephone Birthday ",
"John KononMinistry of Moon Walks 4567882 27-Feb",
"Stacy Kisha Ministry of Man Power 1234567 17-Jan"

I fail to understand how something can "not work" when it is clearly working, and very successfully too, in two different languages.

Since it has headers, it might make more sense for readability to use
a DictReader:
f = file("source.txt", "rb")
r = csv.DictReader(f, delimiter='\t')
for row in r:
print row["Name"], row["Address"], ...
However, if it's just stripping off the first row and operating
directly on the resulting data, then I'd just be tempted to do
r = csv.reader(f, delimiter='\t')
r.next() # discard the headers, or optionally store them
for row in r:
...

After doing:
>>> import csv
>>> original = file('friends.csv', 'rU')
>>> reader = csv.reader(original, delimiter='\t')
Stripping of the first line is:
>>> list(reader)[1:]
If for some reason you want to tuplify each row do either:
>>> [tuple(row) for row in list(reader)[1:]]
Or else
>>> map(tuple,list(reader)[1:])
I usually prefer comprehensions to maps. Here though, the map is
shorter. Your choice
Then you can of course make your code more performant thus:
>>> reader.next()
>>> (tuple(row) for row in reader)
In the majority of cases this optimization is not worth it
In any case, strewing prints all over the code is a bad habit (except
for debugging).

Then you run it, see it spew text to the console, and hit Ctrl-C. Programming is iterative: once you fix one problem, you find the next. Programming is also recursive: in fixing one problem, you sometimes have to deal with others that it depends on. Programming is functional, too: you take a list of problems, apply the "Code" function to them, and keep the list of return values, which will be hopefully-working code.

I know some people will disagree with me, but I recommend on "Dive Into Python" by Mark Pilgrim. It assumes no prior knowledge whatsoever, and it explains all the foundations of the language from the bottom up, without skipping any steps. It also provides many examples that demonstrate how to get Python to do things.

This works for small sources, but slurps all the data into memory.
Because csv.reader is an iterator/generator, it can process huge CSV
files that wouldn't otherwise fit in memory. By using either
r.next() (or "next(r)" in newer versions), it fetches one record from
the generator, to be discarded/stored as appropriate.

If the CSV file is large, using the iterator version is usually worth
the small performance penalty, as you don't have to keep the whole
file in memory. As somebody who regularly deals with 0.5-1GB CSV
files from cellular providers, I speak from experience of having my
machine choke when reading the whole thing in.

Sorry if my print-statements were misinterpreted--I meant them as a

Hi, after fixing the infinite loop, there was a missing line in my first post
inside the while loop I accidentally deleted this line:
i += 1;
Sorry for that.
adding the .py to the file name (the one to import) did fix the problem, thanks
for the help.

You can't. However, you can import explicitly from your package, or implicitly by using a relative import. Starting from Python 2.7, the "import" statement is always absolute. So the line: import collections will always find the first *top level* module or package "collections" in the python search path. See below for an important proviso. Inside your package, you can either use an explicit import like this: import mypackage.collections as collections or use a relative import like this: from . import collections Here is a concrete example. I create a package containing five files: mypackage/ +-- __init__.py +-- collections.py +-- absolute_import.py +-- explicit_import.py +-- relative_import.py with the following content: # absolute_import.py import collections # explicit_import.py import mypackage.collections as collections # relative_import.py from . import collections The other two files (collections.py and __init__.py) can be blank. Now, from *outside* the package, I can do this: py> import mypackage.absolute_import py> import mypackage.explicit_import py> import mypackage.relative_import py> py> mypackage.absolute_import.collections py> mypackage.explicit_import.collections py> mypackage.relative_import.collections Of course "from mypackage import absolute_import" etc. will also work. However, beware: if you cd into the package directory, and then launch Python, the current directory will contain a file "collections.py" which will shadow the standard library collections.py. So don't do that. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
[RELEASE] Python 2.7.4 release candidate 1
I'm happy to announce the first release candidate of 2.7.4. 2.7.4 will be the latest maintenance release in the Python 2.7 series. It includes hundreds of bugfixes to the core language and standard library. There has recently been a lot of discussion about XML-based denial of service attacks. Specifically, certain XML files can cause XML parsers, including ones in the Python stdlib, to consume gigabytes of RAM and swamp the CPU. 2.7.4 does not include any changes in Python XML code to address these issues. Interested parties should examine the defusedxml package on PyPI: https://pypi.python.org/pypi/defusedxml 2.7.4 release candidate 1 is a testing release. Deploying it in production is not recommended. However, please download it and test with your libraries and applications, reporting any bugs you may find. Assuming no horrible bugs rear their heads, a final release of 2.7.4 will occur in 2 weeks. Downloads are at http://python.org/download/releases/2.7.4/ As always, please report bugs to http://bugs.python.org/ Enjoy, Benjamin Peterson 2.7 Release Manager -- http://mail.python.org/mailman/listinfo/python-list

Hi Steven, actually why I need is to know how much memory has been allocated for buffering. getsizeof gets the size of the object structure.

I can see at least four ways to get the current size of the BytesIO buffer: py> obj = io.BytesIO(b"x"*12468) py> obj.getbuffer().nbytes 12468 py> len(obj.getvalue()) 12468 py> len(obj.getbuffer()) 12468 py> obj.seek(0, 2) 12468 As far as I can tell, BytesIO objects do not have a fixed size buffer.

Hi guys, i got into another situation i was told not to use csv library and
currently my code is :
f = open('friends.csv', 'rU')
for row in f:
print [row for (row) in f]
output :
['John Cleese,Ministry of Silly Walks,421,27-Oct\n', 'Stacy Kisha,Ministry
of Man Power,1234567,17-Jan\n']
i need it to become :
[('John Cleese', 'Ministry of Silly Walks', '421', '27-Oct'), ('Stacy
Kisha', 'Ministry of Man Power', '1234567', '17-Jan')]
guide me please
