Mobject

The defined submobject function of Mobject in mobject.py is

• def add(self, *mobjects)
• def add_to_back(self, *mobjects)
• def remove(self, *mobjects)
• def push_self_into_submobjects(self)
• def add_n_more_submobjects(self, n)
• def copy(self)
• def deepcopy(self)
• def repeat_submobject(self, submob)

Submobject Functions

def add(self, *mobjects)

add is used to add the list of specified mobjects to the front of the submobjects of a Mobject.

def add_to_back(self, *mobjects)

add_to_back is used to add the list of specified mobjects to the back of the submobjects of a Mobject.

def remove(self, *mobjects)

remove is used to remove the list of specified mobjects from the submobject list of a Mobject.

def push_self_into_submobjects(self)

push_self_into_submobjects is used to push a mobject itself into the submobject list of the Mobject by self.add().

def add_n_more_submobjects(self, n)

add_n_more_submobjects is used to add n more submobject with respect to the specified n parameter,n into the submobject list of a Mobject accordingly.

def copy(self)

copy is used to return a copy of a mobject itself through copy.

def deepcopy(self)

deepcopy is used to return a copy of a mobject itself through deepcopy.

def repeat_submobject(self, submob)

repeat_submobject is used to return a copy of mobject with respect to the specified submob parameter, submob, of a Mobject.
