Question

I have list in python which has following entries

name-1

name-2

name-3

name-4

name-1

name-2

name-3

name-4

name-1

name-2

name-3

name-4

I would like remove name-1 from list except its first appearance — resultant list should look like

name-1

name-2

name-3

name-4

name-2

name-3

name-4

name-2

name-3

name-4

How to achieve this ?

Answer 1

Assuming name-1 denotes “the first element”:

[names[0]] + [n for n in names[1:] if n != names[0]]

EDIT: If the overall goal is to de-duplicate the entire list, just use set(names).
