You can also use itertools.repeat to do that:

>>> from itertools import repeat
>>> repeatvars = repeat('var', 8)
>>> repeatvars
repeat('var', 8)
>>> list(repeatvars)
['var', 'var', 'var', 'var', 'var', 'var', 'var', 'var']

and there are many useful functions under the itertools module, you can learn it from this site, hope that will help.

You can use list comprehension syntax:

 new_list=[var for i in range(8)]

You can do it with multiplication operator:

new_list = [var] * 8

Also remember that variables store references to objects in Python, so:

ob = MyObject()
new_list = [ob] * 8

will create a list consisting of 8 references to the same object. If you change it - all of them change.
