dict comprehension syntax

gistfile1.md

In Python 2.6 (or earlier), use the dict constructor:

d = dict((key, value) for (key, value) in sequence)

In Python 2.7+ or 3, you can just use the dict comprehension syntax directly:

d = {key: value for (key, value) in sequence}

You may also use:

d = {value: foo(value) for value in sequence}
