统计排序数组中出现次数最多的元素出现的次数？

def get_max_count(l:list):
    dict1={}
    for i in l:
        if i not in dict1:
            c = l.count(i)
            dict1[i] = c
    max_count= sorted(dict1.values())[-1]
    for k,v in dict1.items():
        if v == max_count:
            print("数组中出现次数最多的元素是:%s，出现的次数为：%s"%(k,v))


l1=[1,1,2,2,2,5,5,5,5,5,8,8,8,8,8,8,8,8,8,8,"a","a","a","a","a","a","a","a","a","a"]
get_max_count(l1)
