Batch rename objects with number sequence?

Question

Is there a way to batch rename objects in a sequence similar to: object1, object2, object3...? Where 'object' would be any custom name?

I found the batch rename datablocks script and it was really helpful for renaming a group of objects but gives a sequence like: object.001, object.002, object.003

Is there any way to use this script to give the first kind of sequence?

Blender 2.79

import bpy

for i, obj in enumerate(bpy.context.selected_objects, 1):
    bpy.context.scene.objects.active = obj
    obj.name = "object" + str(i)

Blender 2.8+

import bpy

for i, obj in enumerate(bpy.context.selected_objects, 1):
    bpy.context.view_layer.objects.active = obj
    obj.name = "object" + str(i)

Just replace "object" with "your name" and run this in the text editor (make sure you have all objects selected that you want renamed).

Answer 2

Blender users can now do batch rename with (Menu: Edit ‣ Batch Rename and Hotkey: Ctrl+F2) without any add-ons. (blender +2.80)

An example:

Read this blender manual section for more info: https://docs.blender.org/manual/en/dev/files/blend/rename.html#batch-rename

I'm sure there are dozens of add-ons floating around that do this since they are quite easy to code and thus a good way to learn python, but here's mine:
