I need to do a copy of a list in lower, but I don't want to do it with a loop. Something like this:
I try doing this: `
new_users = ["moresede", "renerico", "antoniogr01", "darknight", "admin"]
new_users_lower = new_user[:].lower()
`

`new_users_lower = [x.lower() for x in new_users]` – WillardSolutions Dec 24 '22 at 17:38

They are already lowercase. `[i.lower() for i in new_users]` ? `list(map(str.lower, new_users))` ? – S.B Dec 24 '22 at 17:39

`lower()` won't have any effect on those specific values... – John Gordon Dec 24 '22 at 17:39

@JohnGordon lol, but the unit tests pass fine! – WillardSolutions Dec 24 '22 at 17:40

2@WillardSolutions that's why the TDD gurus tell you to write a failing test first. – Karl Knechtel Dec 24 '22 at 17:41

The poster specified "don't want to do it with a loop". Is the "for" in comprehension considered to be a loop? – user3435121 Dec 24 '22 at 19:54

@user3435121 Technically yes. I added `map` solution but that is also a loop (in C). – S.B Dec 25 '22 at 09:00
