python-3.x - 将 SAS 代码转换为 KL 散度图的 Python

Question

下面显示的 SAS 代码在翻译成 python 时看起来如何？

/* Plot the K-L div versus lambda for a sequence of Poisson(lambda) models */
lambda = do(4, 16, 0.1);
KL = j(1, ncol(lambda), .);
do i = 1 to ncol(lambda);
   poisPDF = pdf("Poisson", Levels, lambda[i]);
   KL[i] = KLDiv(Proportion, poisPDF); 
end;
 
title "K-L Divergence from Poisson(lambda)";
call series(lambda, KL) grid={x y} xvalues=4:16 label={'x' 'K-L Divergence'};
