PyQT中多重继承,其中继承的父类有QObject或QObject的子孙类

如果Child多重继承(Parent_1,Parent_2,Parent_3)，其super函数

super(Child, self).__init__()

则会执行继承的最左侧的父类:Parent_1.__init__()

但是如果Parent_2是QObject或QObject的子孙类，

在Child的中__init__()中执行QObject.__init__(self)

则会使Parent_3.__init__(self)被执行

原因不明。。。。。。。。。

例子哈：

from PyQt5.QtCore import  QObject

class Parent_1:

    def __init__(self):

        print('Parent_1.__init__')

class Parent_2(Parent_1):

    def __init__(self):

        super(Parent_2, self).__init__()

        print('Parent_2.__init__')

class Parent_3:

    def __init__(self):

        print('Parent_3.__init__')

class Child_2( QObject , Parent_2,Parent_3):

        def __init__(self):

            #QObject.__init__(self)

            super(QObject, self).__init__()

            #super(Child_2, self).__init__()

if __name__ == '__main__':

    import sys

    from PyQt5.QtWidgets import QApplication

    app = QApplication(sys.argv)

 #####################################################

    print('---------------------------')

    child_2 =     Child_2()

  #####################################################

    sys.exit(app.exec_())

输出结果为：
