Oh, wow. I didn't know the dict comprehensions. Since when do they exist? I always used: d = dict((key(x), value(x)) for x in xs)

  Since 2.7, IIRC.

  http://legacy.python.org/dev/peps/pep-0274/ http://legacy.python.org/dev/peps/pep-0274/ I'm not entirely sure how to interpret the PEP header. It dates back to 2001 and was updated in 2012. It's probably in python since 2.3 but maybe 2.7(2010)/3.0(2008).
