如何在一行中重新编写此代码？

Question

是否有一种方法可以用不同于此的方式编写if-else语句？也许更短？

def __init__(self, attributes):
    self.attributes = attributes
    if "yes" in self.attributes:
        self.diabetes = "yes"
    elif "no" in self.attributes:
        self.diabetes = "no"
    else:
        self.diabetes = ""

Answer 1

尝试：

self.diabietes = 'yes' if 'yes' in attributes else 'no' if 'no' in attributes else ''

要进一步改善它，我们需要对attributes类型进行一些假设。

Answer 2

另外两种方式：

self.diabetes = ('yes', 'no', '')[('yes' in attributes, 'no' in attributes, True).index(True)]

或

self.diabetes = [i for i in ('yes', 'no', '') if i in attributes][0]

Answer 3

def __init__(self, attributes):
    self.diabetes = ""
    if "yes" in attributes:self.diabetes = "yes"
    elif "no" in attributes:self.diabetes = "no"
