Python: create a dictionary with list comprehension

Question

I like the python list comprehension operator (or idiom, or whatever it is).

Can it be used to create dictionaries too? For example, by iterating over pairs of keys and values:

dict = {(k,v) for (k,v) in blah blah blah} # doesn't work :(

Answer 1

More or less, but use the dict constructor:

d = dict((k,v) for (k,v) in blah blah blah)

Answer 2

in py3k dict comprehensions work like this:

d = {k:v for k, v in iterable}

in py2k you can use fortran's suggestion.

Answer 3

Use python dict comprehensions: Here's the link to know more about it: Dict Comprehensions
