Title
Body
I need to extract those keys of a dictionary whose values pass a certain condition. Basically, I want to do this, only in a shorter, more pythony way: keys=[] for key in dict: if dict[key]==True: keys.append(key) This was my original idea, but it raises a ValueError: [key for (key,val) in map if val==True] I came up with this for the moment, but I can't help feeling it's not very nice: [key for key in map.keys() if map[key]==True] Is there a less messy way to it? Perhaps something obvious that I'm clearly missing? Thanks!
