Of course, I know that while I'm fresh, I've a good knowledge of the code, and anything else, I will be able to avoid such stupid errors; however, I'm afraid of the times when I'm tired, when I have to put my hands on the code of someone else, and so on.

f.write(pThis is a trial test/p)
f.write(/body/html)
print Content-type: text/html\n
print f.getvalue()
f.close()

Now I am trying to put both the image and the text together, but the
following lines do not create the text with the chart that I expected.
[CODE]
f=StringIO.StringIO()
f.write('htmlheadtitledata analysis site/title/headbody')

f.write(urllib.urlopen(http://localhost/myLibs/ChartLib.py,urllib.urlencode(TheData)))
f.write(/body/html)
print Content-type: text/html\n
print f.getvalue()
f.close()

It looks to me like you are opening the url, but never retrieving the

I think you may have better luck with urllib2 which has a read() method.

That's the IP address the OP probably wants. At least, when I've asked
this exact same question, that's what I meant.
The only way I know of is to query an external server that will tell you.
There's a few of them out there. Here's a few:
http://checkip.dyndns.org/
http://www.showmyip.com
http://www.showmyip.com/simple/
http://whatismyip.org/
The basic algorithm is to connect to one of those sites and fetch the
data it returns, then parse it appropriately. Some of them return a
simple IP address, some a complicated bunch of text, some a nicely
formatted XML document. Some of them only allow you to query the server a
limited number of times. I don't remember which is which.
To get you started, here's an untested piece of code:
import urllib2
import re
data = urllib2.urlopen(site).read()
matcher = re.compile(r\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})
ip_address = matcher.search(data).group()

Re: Q re documentation Python style
On Sun, Jun 8, 2008 at 2:17 PM, kj [EMAIL PROTECTED] wrote: I'm a Perlhead trying to learn the Way of Python. I like Python overall, but every once in a while I find myself trying to figure out why Python does some things the way it does. At the moment I'm scratching my head over Python's docstrings. As far as I understand this is the standard way to document Python code. I think that's fine for simple functions, but I have some functions that require a very long docstring to document, and somehow I find it a bit disconcerting to stick a few screenfuls of text between the top line of a function definition and its body. I guess I'm still a lot more comfortable with Perl's POD, which allows more flexibility on the placement of the documentation relative to the source code. I expect that the reply to this quibble about very long docstrings will be something like: if your function requires several screenfuls of text to document, then it is too complex or it is doing too much; refactor it into a collection of simpler functions that will have shorter docstrings. Fair enough. In general I agree with this sentiment, except that I think that sometimes even simple functions require a lot of documentation. For example, I want to document a function that takes a dictionary as argument, and this dictionary is expected to have 5 keys. (When the number of mandatory arguments gets above 4, I find that it's too difficult to remember their order, so I resort to using a dictionary as the single argument.) The semantics for each of these keys needs to be described. Plus, of course, I need to describe what the function returns. That's a few screenfuls right there... I guess this is a rambling way to ask: are docstrings *it* as far Python documentation goes? Or is there a second, more flexible system? Then again, I suppose that Python's relative formal rigidity is considered by many to be a strength. Which means that, to be comfortable with Python, one has to learn to like this (relatively) rigid structure... But I thought I'd ask. :) Kynn -- NOTE: In my address everything before the first period is backwards; and the last period, and everything after it, should be discarded. -- http://mail.python.org/mailman/listinfo/python-list If you use named parameters in your functions and methods, order is not so important... def foo(a=None, b=None, c=None): ...print a,b,c ... b(c=1, a=2, b=3) 2 3 1 -- Stand Fast, tjg. -- http://mail.python.org/mailman/listinfo/python-list
