How do I get IntelliJ to recognize common Python modules?
Just create and add Python SDK
File -> Project Structure -> Project -> Project SDK -> newand select the installation path of your Python interpreter (forexample, C:\Python26 in windows and /usr/bin/python2.7 in Linux) as the home path.

Have you set up a python interpreter facet?
Open Project Structure CTRL+ALT+SHIFT+S
Project settings -> Facets -> expand Python click on child -> Python Interpreter
Then:
Project settings -> Modules -> Expand module -> Python -> Dependencies -> select Python module SDK
If your Python SDK is properly configured and you are still facing the problem that builtins are not recognized, try this:
File -> Invalidate Caches/Restart
