Django关于TypeError: 'tuple' object is not callable解决方式

在学习《Django企业开发实战》时

写学员管理系统的前台开发始于到了问题

后台报错信息

    from .models import Student
  File "/home/luffy/student_house/student_sys/student/models.py", line 4, in <module>
    class Student(models.Model):
  File "/home/luffy/student_house/student_sys/student/models.py", line 8, in Student
    (0,'unkonw'),
TypeError: 'tuple' object is not callable

在网上查了几个方法没有解决

错误代码

SEX_ITEMS = [
        (1,'man'),
        (2,'famel')
        (0,'unkonw')
    ]

最后重新对照代码发现少打了，

SEX_ITEMS = [
        (1,'man'),
        (2,'famel'),
        (0,'unkonw'),
    ]

就可以运行啦
