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.

BASIC INSTALL INSTRUCTIONS
1- find a directory that is accessible by web url
2- create a new file called index.py 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 http://stackoverflow.com/questions/tagged/python
