There is nothing explicitly wrong with using lambda.  However, unless 
the lambda you are using is easy to understand, you may not understand 
how or why it works later.  The lambda given to you works just fine, but 
if you are afraid of using lambdas, here you go:

def cmp_1(x,y):
     return cmp(x[1], y[1])
