You can also provide a generic except clause, which handles any exception. After the except clause(s), you can include an else-clause. The code in the else-block executes if the code in the try: block does not raise an exception. The else-block is a good place for code that does no...

CPython has a generic dictionary lookup function that handles all types of keys (str, int, any object ...), and a specialized one for the common case of dictionaries composed of str-only keys. The specialized function (named lookdict_unicode in CPython's source) knows all existing keys ...
