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 Outlines - better than folding
With outlines functions and classes can be arranged and grouped with their logical neighbours, even nested. Whole branch hierarchies can be expanded and collapsed in a single key stroke, or moved from this spot to that, as best fits the thinking or troubleshooting of the day. Outline trees make navigation across broadly different areas an effortless exercise. See your whole project in a single view, across any number of external files and modules.
Pro Internal command line
All Leo editor commands are available in a command bar, called a "mini-buffer", that feature tab-completion and command history. For example "Find all nodes containing phrase '...', clone them, and paste in a new tree" is a simple alt-x
, clone-find-flattened
(or cff
) away. As is toggle-split-direction
, expand/contract-log-pane
and execute-script
.
Pro Clones - when two or three or ... are better than one
Leo's unique concept of 'clones' means you can re-arrange sections of an external file to suit your way of thinking or tacking a specific issue without changing the organization of the source. This makes it a great tool for studying code from others, and perhaps contributing back to them without changing your or their preferred arrangement methods.
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 A different way of thinking means learning
There's no other code and text editor quite like Leo, so expect to put in some time learning. It can take some trying this and that before the "Aha!"s start to roll in. It's experiential.
