How to check a value is existing in a list of dictionarys in python

Question

I have a list of dicts like this:

 l = [{"1": "one", "2":"two"}, {"3": "three", "4":"four"}, {"5": "five", "6":"six"}]

I want to check the below value is exist in that list of dicts or not:

 a = "two"

I know we can do this by loop and get() method, I am expecting any alternate method.

You'd have my upvote if you could get rid of [ & ] (generator expressions & early exit)..

How about this one-liner?

>>> l = [{"1": "one", "2":"two"}, {"3": "three", "4":"four"}, {"5": "five", "6":"six"}] >>> any(y == "two" for x in l for y in x.values()) True
