遇到问题了，求解答。

Question

f = open("name.txt", encoding="utf-8")
names = f.readlines()
f.close()
f = open("vote.txt", encoding="utf-8")
votes = f.readlines()
f.close()
D = {}
NUM = 0
for vote in votes:
    num = len(vote.split())  
    if num == 1 and vote in names: 
        D[vote[:-1]] = D.get(vote[:-1], 0)+1   #################
        NUM += 1

l = list(D.items())              ##########################
l.sort(key=lambda s: s[1], reverse=True)          #################
name = l[0][0]
score = l[0][1]
print("有效票数为：{} 当选村民为:{}，票数为：{}".format(NUM, name, score))

哪位可以给我解释一下上边有#的这几句是什么意思

Answer 1

第二个是转化为列表，第三个是按照票数排序
