How to invert a list of strings left to right

Question

I have a bunch of lists and I want to inverse their string content from left to right. How to transform x

x = ['TARDBP', 'BUB3', 'TOP2A', 'SYNCRIP', 'KPNB1']

to

x = ['KPNB1', 'SYNCRIP', 'TOP2A', 'BUB3', 'TARDBP']

x = x[::-1] [This comment](https://stackoverflow.com/a/3911763/7070779) explains it very well. — Huy Vo, Aug 25 '17 at 16:04

You can do something like this:

x = x[::-1]

or this:

x = list(reversed(x))

You can also perform an in-place reverse as follows:

x.reverse()

is `list` optional? – Don Aug 25 '17 at 16:05
@Don because reversed(x) returns a iterator, and the OP wants a list.. do you have anther suggestion ? – Mohamed Ali JAMAOUI Aug 25 '17 at 16:06
You're right. I thought `reversed` returned a list – Don Aug 25 '17 at 16:08

def reverse(L):
  if L == []:
    return []
  else:
    return reverse(L[1:]) + [L[0]]


print(['TARDBP', 'BUB3', 'TOP2A', 'SYNCRIP', 'KPNB1'])
print(reverse(['TARDBP', 'BUB3', 'TOP2A', 'SYNCRIP', 'KPNB1']))
