Accessing non-consecutive elements of a list or string in python

Question

As far as I can tell, this is not officially not possible, but is there a \"trick\" to access arbitrary non-sequential elements of a list by slicing?

For example:

Answer 1

Just for completeness, the method from the original question is pretty simple. You would want to wrap it in a function if L is a function itself, or assign the function result to a variable beforehand, so it doesn't get called repeatedly:

[L[x] for x in [2,5]]

Of course it would also work for a string...

["ABCDEF"[x] for x in [2,0,1]]
['C', 'A', 'B']
