I'm a python beginner and would like to learn how to get the names of the elements in a list. For example, if I have
input = [1, 1, 1, 2.5, 2.5, 'a', 'a']
then I'd like to get
output = [1, 2.5, 'a']
If anyone could help, I'd be very grateful.

Do you need to keep the order? – Kate Melnykova Dec 15 '20 at 00:39

To keep order: `[*dict.fromkeys(input)]` – ssp Dec 15 '20 at 00:42

You can also use numpy, import numpy as np input = [1, 1, 1, 2.5, 2.5, 'a', 'a'] input_unique = np.unique(input) print(input_unique) The result: ['1' '2.5' 'a'] – ibilgen Dec 21 '20 at 06:48
