Can I call a function inside a Lambda expression in python

I have a function with including if, else condition and for loop. I want to write this function inside a lambda expression. I tried from many ways to create this lambda function. But still I couldn't do it. This is my function.

negation ='no,not,never'.split(',')
list2 = 'miss,loss,gone,give up,lost'.split(',')

def f(sentence):
  s = sentence.split()
  l = [s.index(word) for word in s if word in list2]
# Will returns list of indices (of sentence) where word is in list2
   if len(l) > 0:
    for e in l:
        # Check previous word
        if s[e-1] not in negation:
            print 'sad'

Can I express this function inside a lambda expression. Please help me.
