Define a lambda expression that raises an Exception

Question

How can I write a lambda expression that\'s equivalent to:

def x():
    raise Exception()

The following is not allowed:

y =         


        

Answer 1

If all you want is a lambda expression that raises an arbitrary exception, you can accomplish this with an illegal expression. For instance, lambda x: [][0] will attempt to access the first element in an empty list, which will raise an IndexError.

PLEASE NOTE: This is a hack, not a feature. Do not use this in any (non code-golf) code that another human being might see or use.
