<p>Which Eclipse package should I choose for Python development with <a href="http://www.pydev.org/" rel="nofollow noreferrer">PyDev</a>?</p>

<p>Nothing on the Eclipse homepage tells me what to choose, and the PyDev documentation assumes I already have Eclipse installed. Does it matter which Eclipse package I choose?</p>

If you just plan on doing Python dev, I'd just go with
Platform Runtime Binary
.
After that, I'd follow the instructions
http://pydev.org/download.html
and
http://pydev.org/manual_101_root.html
to install PyDev.
I use the same setup for Python development.  I also have the RadRails plugin for Ruby on Rails development.
