Python Stop-Motion Insert Keyframe

Question

I'm creating a stop motion animation that requires to Insert Keyframes of visibility. I was attempting to work out a script to make this process faster for me, but being new to python this has evaded me. Any help would be appreciated.

My work flow goes as:

1. Select object (with mouse)
2. Insert key frame on both viewport and rendering visibility
3. Hide Viewport bpy.context.object.hide = True
4. Hide Rendering bpy.context.object.hide_render = True
5. Move Next Frame
6. Un-hide Viewport bpy.context.object.hide = False
7. Un-hide Rendering bpy.context.object.hide_render = False
8. Insert key frame on both viewport and rendering visibility

Update based on accepted answer

Other then the following comments, I can't find any other issues.

• If you run the script multiple times It will continue to add buttons.
• Also I agree with you on Just inserting a keyframe instead of hiding and adding a keyframe.
• Is there any way to apply the Hide keyframes to multiple items at once? It seems only the last selected item receives the keyframe change.

Also once again a huge thanks, here is a frame of how it turned out!

This adds a button to the 3D View tool panel, Animation tab:

import bpy

class OBJECT_keyframe_insert_hide(bpy.types.Operator):
    """Tooltip"""
    bl_idname = "object.keyframe_insert_hide"
    bl_label = "(Un)hide"
    bl_options = {'REGISTER', 'UNDO'}

    hide = bpy.props.BoolProperty(name="Hide")

    @classmethod
    def poll(cls, context):
        return context.object is not None

    def execute(self, context):
        ob = context.object
        ob.hide = self.hide
        ob.hide_render = self.hide
        ob.keyframe_insert("hide")
        ob.keyframe_insert("hide_render")
        return {'FINISHED'}


def draw_func(self, context):
    layout = self.layout
    hidden = context.object.hide

    layout.label("Stop motion:")
    layout.operator(OBJECT_keyframe_insert_hide.bl_idname, text="Unhide" if hidden else "Hide", icon='KEY_HLT').hide = not hidden

def register():
    bpy.utils.register_class(OBJECT_keyframe_insert_hide)
    bpy.types.VIEW3D_PT_tools_animation.append(draw_func)


def unregister():
    bpy.utils.unregister_class(OBJECT_keyframe_insert_hide)
    bpy.types.VIEW3D_PT_tools_animation.remove(draw_func)


if __name__ == "__main__":
    register()

It hides or unhides the active object and keyframes the .hide / .hide_render properties.
