在使用max之后，如何知道python中哪个变量的值最大？

Question

我在for循环中有一些变量，我必须找到它们中的最高值，以及具有最高值的变量的名称

我使用了：

highest_value = max(a,b,c,d,e)
return highest value

它给了我正确的答案，但我无法识别哪一个变量的值最高

以下是实际代码：

def highest_area(self):
        southeast = 0
        southwest = 0
        northeast = 0
        northwest = 0
        others = 0
    
    for i in self.patient_region:
        if i=="southeast":
            southeast += 1
        elif i=="southwest":
            southwest += 1
        elif i=="northeast":
            northeast+=1
        elif i=="northwest":
            northwest+=1
        else:
            others+=1
    highest = max(southeast,southwest,northeast,northwest,others)
    return highest

如何使用任何内置函数获取最高值的名称

Answer 1

您应该使用字典来存储变量

以下是您的代码-简化：

from operator import itemgetter

def highest_area(self):
        directions = dict(
          southeast = 0
          southwest = 0
          northeast = 0
          northwest = 0
        )
        others = 0
    
    for i in self.patient_region:
        if i in directions:
            directions[i] += 1
        else:
            others += 1
    directions['others'] = others
    # highest_dir has the key, while highest_val has the corresponding value
    highest_dir, highest_val = max(directions.items(), key=itemgetter(1))
    return highest_dir
