>>> s = "start SomeArbitraryAmountOfText start AnotherArbitraryAmountOfText
end"
>>> [t[::-1] for t in re.compile("dne(.*?)trats").findall(s[::-1])]
[' AnotherArbitraryAmountOfText ']
Ok, I'm not serious about this one -- but how about
>>> parts = (t.partition("end") for t in s.split("start"))
>>> [left for left, mid, right in parts if mid]
[' AnotherArbitraryAmountOfText ']
