How can I import an addon into a Blender script?

Question

I want to import an addon into a Blender script

Is this possible, are there any tutorials about it?

Something like from io_scene_3ds.import_3ds import load_3ds to use load_3ds(filepath, context, IMPORT_CONSTRAIN_BOUNDS=10.0, IMAGE_SEARCH=True, APPLY_MATRIX=True, global_matrix=None) code from the import 3ds addon? or do you want to enable the addon in a script? — batFINGER, Jul 19 '16 at 18:37

There are addon utilities available in 2.77/scripts/modules/addon_utils.py which you can import into your script.

Here is an overkill example, lists all addons and then tries to enable addons named ['mesh_looptools','mocap_madness','goose']

import bpy
from addon_utils import check, paths, enable

def get_all_addons(display=False):
    """
    Prints the addon state based on the user preferences.
    """
    import sys
    paths_list = paths()
    addon_list = []
    for path in paths_list:
        bpy.utils._sys_path_ensure(path)
        for mod_name, mod_path in bpy.path.module_names(path):
            is_enabled, is_loaded = check(mod_name)
            addon_list.append(mod_name)
            if display:  #for example
                print("%s default:%s loaded:%s " % (mod_name, is_enabled, is_loaded))                
    return(addon_list)
#print all the addons and show if enabled and default
addons = get_all_addons(True)
#enable dependencies
addon_dependencies = ['mesh_looptools','MocapMadness','goose']
for addon in addon_dependencies:
    if addon in addons:
        is_enabled, is_loaded = check(addon)
        if not is_enabled:
            print("%s enabled" % addon)
            enable(addon)
    else:
        print("Error Dependency %s missing" % addon)

Mainly only need

    is_enabled, is_loaded = check(addon)
    if not is_enabled:
        print("%s enabled" % addon)
        enable(addon)

okay, so would i have to change addon to what the addon is called — Alexander Pagan, Jul 19 '16 at 19:20
Depends on the addon. Addon foo_bar may register an operator "foo_bar" which you would call using bpy.ops.foo.bar() — batFINGER, Jul 19 '16 at 20:15
What im wanting to do is open a 3d view addon from python, ho would i do that — Alexander Pagan, Jul 19 '16 at 20:16
@batFINGER I'm trying to download the latest mocap_madness addon. Could you please share a link of the addon. I found this https://github.com/batFINGER/batFINGER-blender-addons/tree/master/mocap_madness and downloaded it then compressed it as zip file then installed it, but I can't find it in the addons list. — Tak, Oct 31 '16 at 05:10
