Pros
Pro Can be extended to have additional features through plugins
Eclipse has a large and active community, which has resulted in a wide variety of plugins.
Pro Feature rich including Django integration
Django Integration, Auto code completion, Multi language support, Integrated Python Debugging, code analysis, code templates ,smart indent, bracket matching, error markup, source control integration, code folding, UML Editing and viewing, and unit test integration.
Pro Good integration of interactive python console even in debugging mode
Pro Handles non-Python components well
If your project includes non-Python pieces (ie. Javascript, CSS, UML, etc) Eclipse tends to provide much better support for these than IDEs focused exclusively on Python.
Pro Can use different environments for different projects
It's very handy for managing multiple projects that each use their own virtualenv or conda environment, you can assign a different interpreter to each project and they will handle things like code completion correctly.
Pro Good font rendering
Because Eclipse is based on SWT, it uses the native font rendering and thus looks better than other IDEs on some Linux systems, where the Java font rendering is not optimal.
Pro One of the few that can debug Jython code
It handles both Jython and CPython.
Pro Has built-in FTP
Komodo Edit has a built-in FTP client which allows developers to access remotely hosted files.
Pro Free and open-source
Komodo Edit is the free and open-source counterpart of Komodo IDE.
Pro Vim support
Komodo Edit has support for a limited Vim mode.
Cons
Con Just plugin for python, not full editor
It useful only if you use python as additional(secondary) language in your project on Eclipse
Con Plugins can be unstable
Though there are plenty of plugins to choose from, they aren't always reliable. Some aren't maintained, bug fixes can be slow, and you may need to download plugins from multiple sources.
Con Not very lightweight
Komodo Edit is not very lightweight and that can slow it down during startup.
