Ranked in these QuestionsQuestion Ranking
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 Version control integration
PyCharm has CVS, Git, Subversion and Mercurial integration.
Pro Sophisticated autocompletion
PyCharm includes sophisticated heuristics for determining what each variable type is and providing autocompletion suggestions for them.
Pro Excellent refactoring support
There are many refactoring options including renaming and changing signature across entire projects. It also includes the an ability to preview changes before committing and exclude anything unwanted.
Pro Excellent debugger
PyCharm can leverage run-time information when running your application with the built-in debugger to figure out what types can possibly be passed to which functions, etc.
Pro Framework support
PyCharm supports cefpython and electron.js (with c bindings).
Pro Pro features Free for students
JetBrains offers a Student Pack, which gives you a student license and access to the pro features of selected products such as PyCharm, IntelliJ IDEA and Php Storm.
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 Memory-hungry
Can use a lot of memory (several GBs), especially when dealing with large projects.
Con Can sometimes become very slow, freeze, and become unresponsive
It becomes extremely frustrating when you have to wait for the text you've typed to appear in your editor. Furthermore, during these freezes the editor does not always queue what your're typing, so you might have to wait > 15 seconds before you can continue your editing. This quickly affects the concentration of a developer, causing flow interruption and general performance degradation.
Con Feature incomplete
Some features are locked behind a paywall. Although if you are a student, you can apply for the Student Pack.
