获取索引值

一、列表中最大值的索引

a_list = [1,4,7,3,6,2,]
i = a_list.index(max(a_list))

二、np数组中最大值的索引

def max_height(name,height):
    max_height_name = None
    max_height = 0
    for i in range(len(names)):
        name_height =heights[i]
        if name_height > max_height:
            max_height = heights[i]
            max_height_name = names[i]
    return(max_height_name,max_height)

三、利用argmax函数获取array中最大值的索引。

i = np.argmax(heights)
max_height = heights[i]
max_height_name = names[i]
print('{} is {}cm'.format(max_height_name,max_height))
