This is the same as the Python-level :meth:`dict.setdefault`. If present, it
returns the value corresponding to *key* from the dictionary *p*. If the key
- is not in the dict, it is inserted with value *defaultobj* and *defautobj* is
- returned. This function evaluates the hash function of *key* only once,
+ is not in the dict, it is inserted with value *defaultobj* and *defaultobj*
+ is returned. This function evaluates the hash function of *key* only once,
instead of evaluating it independently for the lookup and the insertion.
