n = int(input())
dic  = {}

for _ in range(n):
  w = input()
  if w in dic.keys():
    dic[w]+=1
  else:
    dic.update({w:1})

print(len(dic.keys()))
print(*dic.values())

在里面 module_1.py 导入为 from . import module_2 src.py 将模块1导入为 from pkg_1 import module_1

这是解决办法,你不必担心学生的分数。

list1=['student1',10,20,40,'student2',20,20,40,'student3',20,30,40,'student4',20,10,30]

student_name =[]
student_name_index =[]

for i in range(len(list1)):        
    if type(list1[i]) == int:
        pass
    else:
        student_name.append(list1[i])
        student_name_index.append(i)

student_name_index.append(len(list1)-1)

total_marks=[]

for i in range(1,len(student_name_index)):
    total_marks.append(sum(list1[student_name_index[i-1]+1:student_name_index[i]]))

final_result =[]

for name, mark in zip(student_name,total_marks):
    final_result.append(name)
    final_result.append(mark)

print(final_result)

# output ['student1', 70, 'student2', 80, 'student3', 90, 'student4', 30]
