我正在使用child_process杀死Raspbian Stretch上的python3脚本，但这不起作用。
>>> class Student:
... def __init__(self, student_name, student_id, student_phone):
... self.student_name = student_name
... self.student_id = student_id
... self.student_phone = student_phone
...
>>> obj = Student("ELizaa",1253251,16165544)
>>> print("student name",obj.student_name,"\nstudent id",obj.student_id,"\nStudent phone",obj.student_phone)
student name ELizaa
student id 1253251
Student phone 16165544
>>>
>>> obj = Student("ELizaa",1253251,"016165544")
>>> print("student name",obj.student_name,"\nstudent id",obj.student_id,"\nStudent phone",obj.student_phone)
student name ELizaa
student id 1253251
Student phone 016165544

在服务器端，我确实看到了控制台消息（“子进程已被终止”），但是脚本一直运行，我缺少什么？
