A range object is not a tuple. Nor (since you were probably running
this in Python 2) is a list.
Not probably, certainly (if it wasn't Python 1):
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55) [MSC v.1900 64
bit (AMD64)] on win32

>>> a = range(3)
>>> a += [8, 13]
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
a += [8, 13]
TypeError: unsupported operand type(s) for +=: 'range' and 'list'
