-The most likely explanation is that, since exceptions

-make that case expensive to improve other cases.
+The most likely explination is that,
+the generally faster languages have made ``common cases fast" at the expense
+of the rarer cases. Since exceptions are considered rare, they are made
+expensive to help speed up common actions, such as entering and leaving try
+statements.
+Python on the other hand, while generally slower than the other languages,
+uses exceptions more and has not scarified their performance.
 In addition, languages with high-level representations have a much
 easier time scanning the stack as there is less to decode.
