Standard Python Libraries/Modules Installed on DH and initial Python setup


It appears that DreamHost’s support for new Python users is extremely minimal. This extends to not providing a standard listing of Python modules that are pre-installed or common issues encountered while trying to use Python on DH. Consequently I have manually created the following listing of modules that are installed and a brief description of each as well as some basic tips. Please add your own.

1- find a directory that is accessible by web url
2- create a new file called or index.cgi (if you have that configured)
3- put this in your file:
import pip # get a listing of all active modules
installed_packages = pip.get_installed_distributions()
installed_packages_list = sorted(["%s==%s
" % (i.key, i.version)
for i in installed_packages])
print installed_packages_list #or export to html for browser output
4- make sure your file is chmod 755 to be executable
5- beware of .htaccess files or web server defaults for which extensions get automatically loaded from a browser request for that folder
6- test via shell before browser as the browser ads additional complications
7- lots of code examples at


I’m trying a little app to force familiarizing myself with Python. As I am about to test my understanding of the web parts of the standard library, I thought I’d check DreamHost’s recommended approach. The wiki sent me to the Forum.

Thanks for your post. I’m sure you’ve reduced my fumbling by at least one order of magnitude, probably two.
