Error for if statement in Python

I am trying to write a function which takes a giving 2x2 matrix and checks if one of its elements is large than a certain value. If this is the case, it returns 1, otherwise it should return 0. Up to now I have:

def Is_it_too_large(W_n, max_value):
   value_1 = abs( W_n(0,0) )
   value_2 = abs( W_n(0,1) )
   value_3 = abs( W_n(1,0) )
   value_4 = abs( W_n(1,1) )
   if value_1 < max_value && value_2 < max_value && value_3 < max_value && value_4 < max_value:
       bool = 0
   else:
       bool = 1
   return bool

However, if I test the function with, for example,

A = np.matrix([[1,3,7],[2,8,3],[7,8,1]])
print Is_it_too_large(A,10)

I get the error "invalid syntax". Any ideas what is wrong here?
