strings are not mutable. You are trying to change `slithy`. You need to create a new string: `x[0] = 'fea' + x[0][3:]` – Mike67 Sep 27 '20 at 13:34

You are attempting to modify the 0th element of the list, which is a string.
You would see the same error with this code
s = "slithy"
s[:3] = 'fea'
The reason for the error is that strings are immutable in Python and as such cannot be modified.

In Python strings are immutable. If your expected result is x = ["slifea",.....], this code is wrong and returns that error.
