The second way only works for a list, because slice assignment isn't allowed for strings.

Other than that i think the only difference is speed:

It looks like it's a little.

I have a piece of code here that is supposed to return the least common element in a list of elements, ordered by commonality:

From collections import counter c = counte

The first, [:], is creating a slice (normally often used for getting just part of a list), which happens to contain the entire list, and thus is effectively a copy of the list.

The second, list(), is using the actual.

The notation list means a list of something (but i'm not saying what).

Since the code in test works for any kind of object in the list, this works as a formal method parameter.

Using a type parameter.
