I have below arrays:

T=np.array(['Female','Male','Male','Female','Female','Male'])
Y=np.array([[9],[8],[9],[9],[8],[8]], dtype='uint8')
I am trying to find statistics using lambda function as below:
Stats1=lambda X,T:[[np.mean(x),np.std(x,ddof=1),len(x)] for x in [X[T=='Female'],[X[T=='Male']]]]
Stats2=lambda X,Y:[[np.mean(x),np.std(x,ddof=1),len(x)] for x in [X[Y==9],[X[Y==8]]]]
Stats1 works fine:
[[muF,sigmaF,NF],[muM,sigmaM,NM]]=Stats1(X,T)
But Stats2 gives error:
[[muP,sigmaP,NP],[muN,sigmaN,NN]]=Stats2(X,Y)
