Multiple logical comparisons on a single line for an if statement
提问by mark mcmurray
I want to do multiple comparisons for a logical condition in python but I am not sure of the right way round for the andand or. I have 2 statements.
我想对 python 中的逻辑条件进行多重比较，但我不确定andand的正确方法or。我有 2 个声明。
Statement 1:
声明 1：
#if PAB is more than BAC and either PAB is less than PAC or PAC is more than BAC
if PAB > BAC and PAB< PAC or PAB > BAC and PAC>BAC:
Statement 2:
声明 2：
#if PAB is more than BAC and PAC is less than PAB or if PAB is less than BAC and PAC is less than BAC
if PAB >BAC and PAC<PAB or PAB<BAC and PAC<BAC
Is or-ing the two ands the correct way to go about it?
or-ing这两个ands是正确的方法吗？
Thanks.
谢谢。

Looking at statement 1, I'm assuming you mean:
查看语句 1，我假设您的意思是：
if (PAB > BAC and PAB< PAC) or (PAB > BAC and PAC>BAC):
In which case, I'd probably write it like this (using chained comparisons, docs: python2, python3):
在这种情况下，我可能会这样写（使用链式比较，文档：python2，python3）：
if (BAC < PAB < PAC) or min(PAB,PAC)>BAC:
You can use an analogous form for statement 2.
您可以对语句 2 使用类似的形式。
Having said that, I cannot make your comments in the question's code match up with my interpretation of your conditionals, so it's plausible I don't understand your requirement.
话虽如此，我无法使您在问题代码中的评论与我对您的条件的解释相匹配，因此我可能不理解您的要求。
