Python IDE/Eclipse

[Dave Boland]

I'm looking for a good IDE -- easy to setup, easy to use -- for Python. 
  Any suggestions?

I use Eclipse for other projects and have no problem with using it for 
Python, except that I can't get PyDev to install.  It takes forever, 
then produces an error that makes no sense.

An error occurred while installing the items
   session context was:(profile=PlatformProfile, 
phase=org.eclipse.equinox.internal.provisional.p2.engine.phases.Install, 
operand=null --> [R]org.eclipse.cvs 1.0.400.v201002111343, 
action=org.eclipse.equinox.internal.p2.touchpoint.eclipse.actions.InstallBundleAction).
   Cannot connect to keystore.
   This trust engine is read only.
   The artifact file for 
osgi.bundle,org.eclipse.cvs,1.0.400.v201002111343 was not found.


Any suggestions on getting this to work?

Thanks,
Dave
