如何将实例方法列表赋值给Python类变量？

我有一个可正常运行的类：

class Point:
    def __init__(self):
        self.checks = [self.check1, self.check2]

    def check1(self):
        return True

    def check2(self):
        return True

    def run_all_checks(self):
        for check in self.checks:
            check()

由于实例变量checks并不针对特定实例，我想将其移至类级别，于是做了如下尝试：

class Point:

    def __new__(cls, *args, **kwargs):
        cls.checks = [cls.check1, cls.check2]
        return super(Point, cls).__new__(cls, *args, **kwargs)

    def check1(self):
        return True

    def check2(self):
        return True

    def run_all_checks(self):
        for check in self.checks:
            check()

这个类定义没有语法错误，但运行时抛出了如下错误：

TypeError: Point.check1() missing 1 required positional argument: 'self'

更新：问题已解决 #

借助方案，我实现了支持继承的正确写法：

class ParentFuncs:
    def check1(self):
        print("check1")

    def check2(self):
        print("check2")

    checks = [check1, check2]

    def run_all_checks(self):
        for check in self.checks:
            check(self)


class ChildFuncs(ParentFuncs):
    def check3(self):
        print("check3")

    def check4(self):
        print("check4")

    checks = ParentFuncs.checks + [check3, check4]

ChildFuncs().run_all_checks()
# Output
check1
check2
check3
check4
