Ok, I've understood my mistake.
Now, my list contains a shared entry of an empty object. When an entry
is needed to be changed, I check if the entry is the shared empty
object; in that case I create a new unique instance. If the entry is
already a unique instance, I use it, so the empty object isn

Hi,
I've noticed that if I initialize list of integers in the next manner:
>>> my_list = [0] * 30
It works just fine, even if I'll try to assign one element:
>>> id( my_list[4] )
10900116
>>> id( my_list[6] )
10900116
>>> my_list[4] = 6
>>> id( my_list[4] )
10900044
>>> id( my_list[6] )
1090011
