RDD replace in lambda

Im strugling with one problem RDD file got filename as on example below and if filename start with 'spmsg' then should be replace by 1 else 0 i should adjust my code in first lambda expresion however i cannot find out what im doing wrong

#RDD file

print(rdd3.take(1))

[('3-1msg1', DenseVector([0.0, 0.1255, 0.5695, 0.377, 0.0, 0.2196, 0.4721, 0.2823, 0.2614, 0.3142]))]

RDD4 = rdd3.map(lambda x: 1 if x[0].startswith('spmsg') else 0)# how to change this line to return AS below RDD5 = RDD4.map(lambda cls_vec: LabeledPoint(cls_vec[0], cls_vec[1]) ) print(RDD5.take(1))

expected output

[LabeledPoint(0.0, [0.0,0.16290896085571283,0.6826175329317583,0.0,0.0,0.0,0.40170165983309447...
