Re: Need help with simple OOP Python question
Hi, You are getting same object because you are overriding the dictionary update. Its printing the proper value with the last updated instance of B. If you want to see the two different instances of class B give print self.sub inside the sub_add method in class A.

The code looks like this: - class A: sub = dict() def sub_add(self, cls): obj = cls() self.sub[obj.id] = obj class B(A): id = 'inst' base = A() base.sub_add(B) base.sub['inst'].sub_add(B) print # prints a blank line print base.sub['inst'] print base.sub['inst'].sub['inst'] -- Now, what I get from this is the following: __main__.B instance at 0x01FC20A8 __main__.B instance at 0x01FC20A8 Why is this? What I want is for them to be two separate objects, but it seems like they are the same one. I've tried very hard to get this to work, but as I've been unsuccessful I would really appreciate some comments on this. I'm sure it's something really easy that I just haven't thought of.

Re: Trapping MySQLdb warnings
Hi Tim,
Use this method it will sort tour problem.
def do_query(insert_query):
import warnings
with warnings.catch_warnings():
warnings.simplefilter('error', MySQLdb.Warning)
try:
cursor.execute(insert_query)
conn.commit()
return 'Success'
except MySQLdb.Error, error:
logging.error(Error in insertion %s query is , error)
return 'Failure'
finally:
conn.close()
try:
xyz = do_query(insert_query)
except MySQLdb.Warning, warning:
logging.warning(warning)
you need to use the with statement and then you need to catch the warnings
hope it helps

Have you tried
http://docs.python.org/library/warnings.html#temporarily-suppressing-warnings
Hi Geremy:
I just looked at the docs there. This is a new module (to me), and
I am unsure of the implementation or whether this is what I should
use.
I tried the following :
try :
self.__rdb.execute(S)
except warnings.catch_warnings:
std.mrk('',0,mysql.py:196) ## DEBUG call
## and it does not look like my code modification
## is catching the warning.
Well, I am so far, absolutely baffled. I've looked at the docs for
the `warning' module. No real examples that I can see. and why has
the _mysql_exceptions.Warning exception no longer working?
grrr..
Be good to hear some other experiences here.
thanks

Re: Python documentation too difficult for beginners
If you are really beginner in python you can look into the dive into python,search as in google as the same its quite helpful for beginners.Also you can go for the byte of python.

Others have mentioned this apparently for years (see: http://stackoverflow.com/questions/4046166/easy-to-navigate-online-python-reference-manual/4070851 and http://www.russellbeattie.com/blog/python-library-docs-still-suck and http://xahlee.org/perl-python/xlali_skami_cukta.html). Compare for instance the differences in ease of use, and speed of use, of these: http://docs.python.org/library/functions.html#open http://uk.php.net/manual/en/function.fopen.php The former is difficult to find (try searching for 'open' in the search box and see what you get). It is simply a collection of paragraphs without strong enough contrast to differentiate the different parts - parameters, parameter values, return types, exceptions and related functions. It is slow to read and doesn't allow easy visual scanning. The latter has clearly delineated, standardised content areas for each of these without excessive text. It uses tables which are easy to scan for possible opening modes and allows users to contribute their own examples. Sadly, the use of restructured text by python doesn't allow a new document generator to be written - all existing documentation would need updating with docblocks or something similar. Has anyone else struggled while trying to learn the language? The whole documentation system seems geared towards people who already know what they're looking for and is close to useless for beginners. I'm not the only one who finds google an easier way to find documentation about python. Is there much chance that the Python maintainers will change their documentation system to make it more like Java or PHP? How would I go about trying to make that happen? -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
