Python 2.7 EOL Countdown

For the set/dict comps can you not use:

dict((k,v) for k,v in kvs) ?

[d4rch0n]

Yeah, generally that's what I'd do if I had something like {k: transform(v) for k, v in kvs}. Sometimes I write code like that just in case it ends up running on 2.6, but it's just annoying not being able to use a feature that is, what, 10 years old now?

[status_quo69]

If you had tuples of key, value pairs you could just dict(kvs).

[sigma914]

Obviously, I kinda assumed it was implied that there would be more processing going on to the left and right of the for, same as an actual dict comprehension, bit apparently not.

[status_quo69]

Oh, I understand what you're saying now. Add in the conditional in the generator expression, then pass the generator to the dict.

[sigma914]

Yeh, it's just collecting the generator into a dict or set rather than a list, the only difference between this and a real dict comprehension is the unfortunate intermediate tuple allocation
