【问题描述】：

print('welcome to the marklist of the students program')
def student(dict):
    for name,marks in dict.items():
        if marks>60:
           print(f'student {name} has got a total of {marks} marks in exam and\n passed the exam with distinction ')
        elif marks>40:
            print(f'student {name} has got a total of {marks} marks in exam and\n passed the exam with first class ')
        elif marks>20:
            print(f'student {name} has got a total of {marks} marks in exam and\n passed the exam with second class ')
        else:
            print(f'student {name} has got a total of {marks} marks in exam and\n ha failed his exam ')

m={}
while True:

  a=input('enter student\'s name:')
  m=int(input('enter students marks in maths:'))
  c=int(input('enter student\'s marks in chemistry:'))
  p=int(input('enter student\'s marks in physics:'))
  cs=int(input('enter student\'s marks in computer science:'))
  t=m+c+p+cs
  m[a]=t
  b=input('want to add another students details?? enter yes or no:')
  if b=="yes":
      continue
  else:
      break

student(m)

所以我想制作一个程序来计算学生的分数并显示学生所属的类别，但是...... 当我运行这个程序时，它给了我一条错误消息
line 22, in <module> m[a]=t TypeError: 'int' object does not support item assignment 我不知道如何解决这个问题请帮助.... 这也是我的第一个问题，如果这个问题有任何错误，请告诉我，以便我可以继续纠正，不要再犯错误

【问题讨论】：

您有两个名为 m 的变量：一个 dict (m={}) 和一个 int (m=int(input(...)))。
请不要保存字符 - 如果您使用更长的变量名，您不会自己绊倒。
使用名称dict（以及list、str 等）作为变量是不明智的。
感谢您的建议，我会记住这一点

【解决方案1】：

您已将m 用于dict 和maths 得分。你可以更新你的代码并试试这个：

print('welcome to the marklist of the students program')
def student(dict1):
    for name,marks in dict1.items():
       if marks>60:
           print(f'student {name} has got a total of {marks} marks in exam and\n passed the exam with distinction ')
      elif marks>40:
            print(f'student {name} has got a total of {marks} marks in exam and\n passed the exam with first class ')
      elif marks>20:
           print(f'student {name} has got a total of {marks} marks in exam and\n passed the exam with second class ')
      else:
           print(f'student {name} has got a total of {marks} marks in exam and\n ha failed his exam ')

m={}
while True:

 student_name=input('enter student\'s name:')
maths_score=int(input('enter students marks in maths:'))
chemistry_score=int(input('enter student\'s marks in chemistry:'))
physics_score=int(input('enter student\'s marks in physics:'))
cs_score=int(input('enter student\'s marks in computer science:'))
t=maths_score+chemistry_score+physics_score+cs_score
m[student_name]=t
b=input('want to add another students details?? enter yes or no:')
if b=="yes":
   continue
else:
   break

student(m)

另外：使用words 定义变量

输出：

welcome to the marklist of the students program
enter student's name:hari
enter students marks in maths:100
enter student's marks in chemistry:100
enter student's marks in physics:100
enter student's marks in computer science:100
want to add another students details?? enter yes or no:no
student hari has got a total of 400 marks in exam and
 passed the exam with distinction
