Question

我遇到一个问题，就是在定义所有学生的分数并去增加分数之后。它没有给我一个错误，但是只是在此处结束了代码。

代码中断的地方：

def particular_class():
  sname = input("Students name?: ")
  for students in Students:
    if (students == sname):
      print("""
      1. Math
      2. English
      3. Comp Sci 
      4. Science
      5. History
      6. French
      7. Quit""")
      grade = int(input("What subject would you like to input a grade for?\n"))
      if grade == 1:
        Math.Add_grades(Students[students])
      elif grade == 2:
        English.Add_grades(Students[students])
      elif grade == 3:
        Comp_sci.Add_grades(Students[students])
      elif grade == 4:
        Science.Add_grades(Students[students])
      elif grade == 5:
        History.Add_grades(Students[students])
      elif grade == 6:
        French.Add_grades(Students[students])
      elif grade == 7:
        Choice()

Answer 1

因为没有名字的学生，所以没有选择，例外之类的电话。我建议使用while True:进行菜单，而不是每次都进行递归调用。您的方法将很快使堆栈溢出。

为什么此代码在此行之后不运行？
