我一直收到错误 AttributeError :
'_tkinter.tkapp' object has no attribute 'getitems'
我认为这是因为子例程无法相互通信我曾尝试将 get_items 分配为全局变量但没有结果。我正在尝试制作一个按钮，用于收集 GUI 中的条目，使用 Sql Lite 将它们输入数据库，用于汽车经销商的库存系统。

conn = sqlite3.connect("E:\computing project\database of cars.db")
c=conn.cursor()

最佳答案
我看到两个错误:
首先:您定义了方法get_items(名称中带有_)但是您使用了command=self.getitems (名称中没有 _)
self.b = Button(command=self.get_items)
第二:你的参数顺序错误是
__init__(kwargs, self, master=None, *args)
因此它将类实例分配给变量 kwargs 而不是 self 并将 root 分配给 self 及以后找到 self.get_items 有问题，因为它意味着 root.get_items
kwargs应该在最后，self在开头
__init__(self, master=None, *args, **kwargs)
关于python - 收到错误 AttributeError : '_tkinter.tkapp' object has no attribute 'getitems' ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56894653/
