Python-找不到内部类 [英] Python - Inner Class Not Found

问题描述

(对不起，我是Python的新手)

(Sorry I'm new to Python)

我正在运行python django脚本，如下所示:

I'm running a python django script as follows:

python3 manage.py测试

class Command(NoArgsCommand):
    help = 'Help Test'
    def handle(self, **options):
        gs = self.create_goalscorer(1,"Headed")

    class GoalScorerX(object):
        id = 0
        goal_type = ""
        #Constructor
        def __init__(self, id, goal_type):
           self.id= id
           self.goal_type = goal_type

    def create_goalscorer(self,id,goal_type):
        gs = GoalScorerX(id, goal_type)
        return gs

但是我收到找不到它的错误?

But I get the error that it can't be found?

    gs = GoalScorerX(id, goal_type)
NameError: name 'GoalScorerX' is not defined

推荐答案

内部类在Python中很少有用.当然，通过将GoalScorerX设置为内部类并不会获得任何好处.将其移到外面；还请注意，Python中文件中类的数量没有限制，因此可以将它们都作为顶级类很好.

Inner classes are very rarely useful in Python. Certainly here there is nothing to be gained by making GoalScorerX an inner class. Move it outside; also note that there is no restriction in Python in the number of classes in a file, so it's fine to have them both as top-level classes.

(请注意，您可以通过将内部类称为Command.GoalScorerX来解决此问题，但不要这样做.)

(Note, you could fix this by referring to the inner class as Command.GoalScorerX - but don't do that.)
