求各位能帮我解答一下这个问题

dic = {x:0 for x in range(8,17)}
with open(r'data.txt', 'r', encoding='utf-8') as fileObj:
    for line in fileObj.readlines():
        print(line)
        n,t,k = line.strip().split(" ")
        if k=="0":
            dic[int(t[0:2])] +=1
for k,v in dic.items():
    print(f"{k}点叫号人数:{v}")

如有帮助，望采纳！谢谢!
