I have two methods for writing binaries files: the first works with
data received by a server corresponding to a file upload, and the
second works with data sent as email attachments.
The odd thing is, they're not interchangeable: if I use the first one
to saved data parsed from an email

And where might we be able to see that stack trace?
This is it:

Which is *really* difficult (for me) to read. Any chance of providing a
normal traceback?

Were you getting this issue with xml.dom showing on first request all
the time, or only occasionally occurring? If the latter, were you
running things in a multithreaded configuration and was the server
being loaded with lots of concurrent requests?
It was the former.
For your particular
His problem is therefore likely to be something completely different.
You are correct.
As per the earlier advice, I switched from mod_python to mod_wsgi but
I still see the same error:
[Mon May 11 10:30:21 2009] [notice] Apache/2.2.11 (Unix) mod_wsgi/2.4

For the record, and in case anyone else runs into this particular
problem, here's how resolved it.
My original xml_utils.py was written this way:
from xml.dom import minidom
def parse_item_attribute (item, attribute_name):
item_doc = minidom.parseString(item)
...
That version worked
I wrote a python script called xml_utils.py which parses xml using
minidom.
It works when it's run on its own, but when I try to import it and run
it inside a mod_python handler, I get this error:
File ../common/xml_utils.py, line 80, in parse_item_attribute

I wrote this function to retrieve a list of items from a dictionary.
The first time it was called, it worked properly.
But every subsequent call returned the results of the prior call, plus
the results of the current call.
I was confused until I read in the docs that default arguments are
The usual solution is:
def get_prior_versions (item_id, priors=None):
if priors is None:
priors = []
Thanks!

How about:
def get_prior_versions (item_id, priors=None):
Return a list of all prior item ids starting with this one
global history_db # key = item id, value = prior item id
prior_id = history_db[item_id]
if not prior_id:
return priors
else:
if priors:
You'll continue to be confused if you use that term. Python already
has a specific use of the term “immutable”, and it doesn't apply
here.
I was just following the terminology used in A Byte of
Python (which, that particular point aside, is a very good tutorial).
Better to say: default
How about this then:
def get_prior_versions (item_id, priors=None):

global history_db # key = item id, value = prior item id
prior_id = history_db[item_id]
if not prior_id:
if priors:
return priors or []
I'm using the feedparser library to extract data from rss feed items.
After I wrote this function, which returns a list of item titles, I
noticed that most item attributes would be retrieved the same way,
i.e., the function would look exactly the same, except for the single
data.append line

I have some old Common Lisp functions I'd like to rewrite in Python
(I'm still new to Python), and one thing I miss is not having to
declare local variables.
For example, I have this Lisp function:
(defun random-char ()
Generate a random char from one of [0-9][a-z][A-Z]
(if ( 50 (random
return chr( random.randrange(0, 26) + (97 if random.randrange(0,
100) 50 else 65)
or
return chr( random.randrange(0, 26) + [26,97][random.randrange(0,
100) 50]
Ah, thanks, these are the syntax examples I was looking for.
but what's wrong with you original code?
I come from a
Any time you port between languages, it's rarely a good idea to just
convert code verbatim. For example:
import random, string
def random_char():
return random.choice(string.ascii_letters + string.digits)
Good point, and thanks for the idiomatic Python example (I like the
conciseness);
If I define a dictionary where one or more of the values is also a
dictionary, e.g.:
my_dict={a:string, b:string, c:{x:0,y:1},
d:string}
How can I use the output of type() so I can do one thing if the value
is a string, and another if the value is a dictionary?
i.e., I'd like to define a loop
