Say I have a list of tuples, I extract the first tuple from this list and then want to create a new list that simply takes the first tuple and repeats it n times creating a list
Since tuples are immutable you may be able to do:
lst = [tuples[0]] repeated = lst * 10 # create a list of the first tuple repeated 10 times
If they contain mutable objects changes in any of them will reflect in all of them, since these are the same objects repeated.
