descriptor 'append' requires a 'list' object but received a 'int'

This error occurs when you try to use the "append" method on an integer object, but the method can only be used on a list object.

For example, if you try to add an integer to a list using the "append" method:

my_list = [1, 2, 3]
my_list.append(4)

This will work fine, and the list will now contain [1, 2, 3, 4].

However, if you try to use the "append" method on an integer object directly:

my_int = 5
my_int.append(6)

This will raise the "descriptor 'append' requires a 'list' object but received a 'int'" error because the "append" method can only be used on a list object.

TypeError: descriptor strftime requires a datetime.date object but received a str

这错误提示意味着 strftime 函数需要一个 datetime.date 对象作为参数，但是你传递了一个字符串。你需要将字符串转换为 datetime.date 对象，然后再调用 strftime 函数。你可以使用 datetime 模块中的 strptime 函数将字符串转换为 datetime.date 对象，然后再调用 strftime 函数。

descriptor '__init__' requires a 'super' object but received a 'str'

这个错误是因为在子类中重写了父类的__init__方法，但是没有调用父类的__init__方法，需要在子类的__init__方法中使用super()来调用父类的__init__方法。可能是因为传入的参数类型错误导致的。
