The standard library, my personal code, third-party packages, and my employer's code base are filled with examples of the following pattern:
try: import threading except ImportError: import dummy_threading as threading
try: import xml.etree.cElementTree as ET except ImportError: try: import cElementTree as ET except ImportError: import elementtree.ElementTree as ET
try: from cStringIO import StringIO except ImportError: from StringIO import StringIO
try: import readline except ImportError: pass
How about a new, simpler syntax:
import threading or dummy_threading as threading
import xml.etree.CElementTree or cElementTree or elementree.ElementTree as ET
from cStringIO or StringIO import StringIO
import readline or emptymodule
