This is not possible in python because when you remove the a[1] then
whole index changes.

probably you can do like this

In [18]: import copy

In [19]: a = [12, 12, 1321, 34, 23, 12, 34, 45, 77]

In [20]: templist = cop

In [20]: templist = copy.copy(a)

In [21]: for index in templist:
   ....:     a.remove(index)
   ....:
   ....:

In [22]: a
Out[22]: []
