I have had issues running a simple "Hello World" py file in Eclipse. Initially I used the Linux software center to get an image of Eclipse and after numerous attempts to resolve, I tried to address the issues on the ubuntu forums. I removed all java files and downloaded JDK 7 and installed that via the terminal line. I then downloaded and installed Eclipse from the main site, installed in my home folder and used the help menu to download the Pydev software from pydev.org/updates. The Py file opens in the IDE, however when I try to run it the run window opens with only the option to run it as an 'Ant' file. Please can someone help me configure Eclipse for Pydev so it can edit and run files of this type?
Thanks for your consideration

First, never ever obtain Eclipse through any Linux software distribution
center. Always get it from eclipse.org.
The PyDev site appears to encourage questions on stackoverflow.com using
the PyDev tag.

Eclipse isn't an editor. It's an IDE and, with respect to PyDev (Android
is another perfect example), it's a framework in which just about any
project can develop extensions to make their own IDE. Sometimes the
seams fray and show difficulty. How well problems are resolved is a
testimony to how much support there is for it.
Don't confuse PyDev with Eclipse (or Android Development with Eclipse).
I have not used PyDev and have no opinion about it. It's not supported
by this forum. So you're not judging it under adequate light.
I have used Android tools. They work pretty well all things considered,
but similarly this isn't the forum in which to ask about them and
judging them by this forum is unfair.
Etc.
Best of luck.

Here's what I'd do. You can read ooey-gooey verbiage at
http://www.javahotchocolate.com/tutorials/eclipse-summary.html
if you want, but these are the steps you can follow if you know how.
Realize that this is how I do it. Others may do it differently. Also, my
instructions assume you're going to develop Java applications. This
won't hurt you if all you're going to do is Python.
1. Download and explode a private Sun JDK (from java.sun.com).
2. Download and explode Eclipse somewhere under /home/hugh.
Which package is best for Python? Beats me, but I'm sure
Eclipse IDE for Java Developers will not hurt you any.
3. Edit eclipse.ini by examining http://wiki.eclipse.org/Eclipse.ini.
You'll want to add the following:
...
-vm
/home/hugh/where-I-put-my-JDK/bin/java
-vmargs
...
4. If you want to create a launcher, do that:
a. Create launcher.
b. Filesystem path is /home/hugh/.../eclipse/eclipse.
c. For icon, use /home/hugh/.../eclipse/icon.xpm
5. Launch Eclipse.
6. Trouble? Come back here.

Oh yeah, I forgot, now for the PyDev bit...
Once Eclipse is up and running, you'll use Help -> Eclipse Marketplace.
In Find: type pydev
You can take it from here. I think you just click on the Install button
at the bottom right of PyDev - Python IDE for Eclipse.
Best of luck,
Russ

(You were on Linux, right?)
eclipse.ini doesn't come with the -vm option in it. When you run Eclipse
without it, it just runs on whatever JRE happens to be available on the
search path.
You pick the directory you want and explode the tarball you downloaded
from eclipse.org there. For instance:
/home/hugh $ tar -zxf eclipse....tgz
/home/hugh $ cd eclipse
/home/hugh/eclipse $ vim eclipse.ini
....
-vm
/home/hugh/jdk1.0.6_20/bin/java
....
:wq
/home/hugh/eclipse $ ./eclipse
....and you're running.

Oh, yeah, I forgot, you moved Java to under eclipse. That wasn't
necessary, but it is a way to solve the problem. In that case, you don't
need to add the -vm option.

The problem is that this has to do with PyDev in Eclipse, which isn't
supported by any Eclipse forum. According to the PyDev web page, their
idea of support is to ask the question in stackoverflow.com carefully
applying the PyDev tag. I've found stackoverflow to be hugely successful
and lightning fast (no pun intended) for answers, especially as compared
to other forums I hang out in.
Best of luck,
Russ

They are legion.
In particular, I suggest http://www.vogella.de.
