Ruby rpartition vs partition?

Question

What is the difference between rpartition and partition? I have read the documentation but I see them like the same. Is it just that ones came up in a later ruby version?

Answer 1

The following example will help identify the difference:

"abccba".partition("b")
# => ["a", "b", "ccba"]

"abccba".rpartition("b")
# => ["abcc", "b", "a"]

So the difference is that rpartition searches for the rightmost occurrence, instead of the leftmost one.
