if else问题的相关代码是？

我想知道你的df是不是总是小于等于3行（我是从你判断的函数觉得你每种药最多是一行的，否则var2[var1==1]>0.9这样会出现很多T或F），如果是，我建议你不要用var2[var1==1]这样的索引方式，而是按照药物编号排序后，if有3种药要怎样，有2种药要怎样，这样逻辑会清晰一点

A few things to clarify:

If the cure rate of drug 1 is greater than 0.9 then there will not be any drug that is 20% better, will it (meaning the drug has a cure rate greater than 1.25 according to your code)?

Drug 2 will be recommended if and only if the cure rate of drug 2 is at least 20% better than drug 1 and is better then drug 3? The same is for drug 3?

Is there an error on lines 9-10 and 16-17? Impossible to recommend drug 3?
