Listing modules from all installed packages
Hi, I'm trying to write a function that programmatically obtains and returns the exact location of all first-level modules for all installed packages. For example, if the packages named 'django' and 'django-debug-toolbar' are installed, I'd like this function to return something like: >>> installed_modules() /Users/my_user/.virtualenvs/my_venv/lib/python2.6/site-packages/django /Users/my_user/.virtualenvs/my_venv/src/debug_toolbar That is, this function needs to consider all installed packages, including those that have been installed in "edit" mode (i.e. in the src/ folder). Note also that the main module for the 'django-debug-toolbar' is in fact named 'debug_toolbar'. So far the closest I've been to retrieving the list of first-level modules is as follows: import os import pkg_resources import setuptools pkgs = set() for dist in pkg_resources.working_set: if os.path.isdir(dist.location): for pkg in setuptools.find_packages(dist.location): if '.' not in pkg: pkgs.add(pkg) The idea is then to loop through that list of modules, import them and get their exact locations by fetching their __file__ attribute values. However, this feels very hackish and I don't think it's actually quite correct either. I'm sure there must be a better way. If possible I'd also like to avoid having to use setuptools. Do you have any tips on how to achieve this? Many thanks! Julien -- http://mail.python.org/mailman/listinfo/python-list

Preserving unicode filename encoding
Hi, I've noticed that the encoding of non-ascii filenames can be inconsistent between platforms when using the built-in open() function to create files. For example, on a Ubuntu 10.04.4 LTS box, the character u'ş' (u'\u015f') gets encoded as u'ş' (u's\u0327'). Note how the two characters look exactly the same but are encoded differently. The original character uses only one code (u'\u015f'), but the resulting character that is saved on the file system will be made of a combination of two codes: the letter 's' followed by a diacritical cedilla (u's\u0327'). (You can learn more about diacritics in [1]). On the Mac, however, the original encoding is always preserved. This issue was also discussed in a blog post by Ned Batchelder [2]. One suggested approach is to normalize the filename, however this could result in loss of information (what if, for example, the original filename did contain combining diacritics and we wanted to preserve them). Ideally, it would be preferable to preserve the original encoding. Is that possible or is that completely out of Python's control? Thanks a lot, Julien [1] http://en.wikipedia.org/wiki/Combining_diacritic#Unicode_ranges [2] http://nedbatchelder.com/blog/201106/filenames_with_accents.html -- http://mail.python.org/mailman/listinfo/python-list
Re: Problem connecting to SMTP/IMAP server using SSL
Hi Michael,
Thanks again for your reply. I've tried using SMTP with TLS. And again it works
with the VPN turned on but it still won't work with the VPN turned off. For
some reason I don't understand, it simply won't instantiate the
SMTP/SMTP_SSL/IMAP4/IMAP4_SSL objects at all and will hang forever if the VPN
is turned off.
I'm really at loss there :)

Do you know why it won't work with SSL and without the VPN? Am I
