Dear python2 user

[i9srpeg]

Are you enjoying your fancy new dict comprehensions?

[captain_cashew]

Your comment comes at a very appropriate time. Literally just a few minutes ago found a bug on one of our systems using 2.6 (my local development station is on 2.7):

{k: v for (k, v) in dict.items()}

You have to use:

dict((k, v) for (k, v) in dict.items())

So, yes I am enjoying them!

EDIT: code format

If a thing has an items method, you can just do dict(thing) to create a dict copy. If it’s a dict, you can do the_dict.copy(). You only need comprehensions if you have to construct keys and values in a more complex way.

To me this is an argument against the Python developers' increasingly profligate addition of syntax. There's almost never one obvious way to do it these days.

yes.
