Check if namedtuple with value x exists in list
Question: I want to see if a namedtuple exists in a list, similar to:

    
    
    numbers = [1, 2, 3, 4, 5]
    if 1 in numbers:
          do_stuff()
    

is there a pythonic (or not) way to do this? Something like:

    
    
     namedtuples = [namedtuple_1, namedtuple_2, namedtuple3]
     if (namedtuple with value x = 1) in namedtuples:
          do stuff()
    


Answer: Use [`any`](http://docs.python.org/2/library/functions.html#any):

**Demo:**

    
    
    >>> from collections import namedtuple
    >>> A = namedtuple('A', 'x y')
    >>> lis = [A(100, 200), A(10, 20), A(1, 2)]
    >>> any(a.x==1 for a in lis)
    True
    >>> [getattr(a, 'x')==1 for a in lis]
    [False, False, True]
