python - Check if a sublist contains an item

I have a list of lists in Python. As illustrated below, I want to check if one of the sublists contains an item. The following attempt fails. Does anyone know of a simple way -- without me writing my own for loop?

>>> a = [[1,2],[3,4],[5,6],7,8,9]
>>> 2 in a

I was hoping for True but the return was False
