Which is more obscure?

Reverse a string in ruby: string.reverse()

Reverse a string in python: string[::-1]

Slice syntax in Python always bothered me. This would be slightly more readable:

    ''.join(reversed(string))

Except it requires you to have an idea of how iteration works (beginners don’t) and why that “join” needs to be there, and it’s still an order of magnitude slower. But hey. Ruby is prettier in some ways, Python in others, and beggars, as they say, can’t be choosers.

Way way slower than the slicing.

What an odd example. Other than perhaps a palindrome detector, I'm having a really hard time coming up with a use for a reversed-strings. Python DOES provide a reverse for arrays.
