This is where a nested for loop works better. The first loop (parent loop) will go over the words one by one. The second loop (child loop) will loop over the characters of each of the words. words=["Apple","Banana","Car","Dolphin"]forwordinwords:#This loop is fetching word from...
In a related change, whenever it is feasible without breaking backwards compatibility, exceptions raised during encoding and decoding operations are wrapped in a chained exception of the same type that mentions the name of the codec responsible for producing the error: >>> >>> import codecs >>...

The sorted built-in looks into the dictionary, and sort the keys based on the values as defined by key=sizes.get. Use reverse=True so that the largest values are first. In the final loop, instead of going through every path, slice the list for the first ten items, and lastly, when ...
