1楼:故事
以下是**:
all_tuple =
sum_stu = int(input('请输入一共有多少个学生:'))
while(sum_stu>0):
a = input('请输入学生名字:')
class1 = float(input('第一门课
的成绩:'))
class2 = float(input('第二门课的成绩:'))
class3 = float(input('第三门课的成绩:'))
score = class1 + class2 + class3
mid = score/3
one_tuple = (a,class1,class2,class3,mid,score)
sum_stu -= 1
sorted_list = sorted(all_tuple,key=lambda x:x[5],reverse=true)
sum_stu = 1
for i in sorted_list:
print('第',sum_stu,'名',i[0],':',end='')
print('平均分:',i[4],',总分:',i[5])
sum_stu += 1
求大佬!请问一道python题目,求助!
2楼:
使用集合,首先分别创建1,2,3科目的集合,使用并集算出人数后用总人数减去求出第一题
第二题,第三题同理
求助大佬,这个python作业的**要怎么写?

print(read_data)
f.close()效果图
求助大佬,这个python作业的**要怎么写?

效果图我看题目没有回说要类型转
答换的就没有转换,有问题继续追问
请问大佬,这道python题目应该怎么写?

#elsesum>4:这个**写错了
12楼:匿名用户
应该是elif sum > 4:
另外,不要用系统关键字做变量
13楼:【掌天
上面的回答只说了你的错误,其实你这样写,else压根进不去,内应该这样写容
sum=0
whiletrue:
name=...
password=...
if...:
print...
break
else:
ifsum<=4:
...else:
...break

第五行s那个是小括号
如果abc都在
版一行要用
