Is there a way to perform “if” in python's lambda

Question

In python 2.6, I want to do:

f = lambda x: if x==2 print x else raise Exception()
f(2) #should print \"2\"
f(3) #should throw an exception
<         


        

Answer 1

what you need exactly is

def fun():
    raise Exception()
f = lambda x:print x if x==2 else fun()

now call the function the way you need

f(2)
f(3)
