         This dictionary stores the evaluation results of all the items in watchlist.
         Example: with a watchlist containing [(dtest,'eval'), (dtrain,'train')] and
-        a paramater containing ('eval_metric', 'logloss')
+        a paramater containing ('eval_metric': 'logloss')
         Returns: {'train': {'logloss': ['0.48253', '0.35953']},
