Python: Install Ruby Gems in Virtualenv
Putting this in your postactivate script will install Ruby Gems in your Python virtualenv:
export GEM_HOME="$VIRTUAL_ENV/gems" export GEM_PATH=""
Python: bpython
bpython is a Python shell similar to ipython. I've been playing around with it lately and prefer it to ipython. It's missing the ? and ?? functions but the inline syntax highlighting and the as-you-type autocompletion are very nice.

Alfred App: Search Django Docs
If you want to search the django docs via Alfred App, you can set up a custom search using django.me.
Go to Features -> Custom Searches and enter the settings as shown in the screenshot above.
Now you can launch Alfred App and enter "django filters". This will redirect you to the built-in filters page of the django docs. If no redirect URL could be found, django.me will ask you to provide one. Please make sure to create a proper link to corresponding Django docs page.
Python: lxml tostring encoding
lxml’s tostring function has an “encoding” option, which you can use to specify an output encoding such as unicode:
from lxml.html import tostring print tostring(doc, encoding=unicode)
Python: Pydoc in a Virtual Environment
Pydoc can be used to search documentation of Python modules:
pydoc os.path
However, this won’t work in a virtual environment since the pydoc command uses the system library and won’t include the ve’s site-packages. To fix this, use the following cmd:
python -m pydoc BeautifulSoup
PS.: Pydoc can also serve documentation on a local webserver (python -m
pydoc -p 8000)
