Is there any work in progress in order to support source code analyzer in PyDev, such as PEP 8 - Style Guide for Python Code? Is there any plug-in similar to Eclipse Checkstyle Plug-in?
PEP 8 - http://www.python.org/dev/peps/pep-0008/
Eclipse Checkstyle Plug-in - http://eclipse-cs.sourceforge.net/
You can use PyLint (http://pydev.sf.net/pylint.html) in pydev for those checks.
Pydev Extensions has a source code-analyzer (http://fabioz.com/pydev/manual_adv_code_analysis.html), but it currently does not make coding-style checks (only checks programming errors, such as unresolved imports, unresolved variables, unused imports, etc).
