Best used on 1 level-deep key:value pair dictionaries (a flat dictionary) and not nested data-structures which are also commonly used with dictionaries. (a flat dictionary resembles a json and a flat list an array for javascript people). +Uses the .keys() method of "dict" objects. dict.keys() returns a view object that displays a list of all the keys. Then, list(dict.keys()) returns a list that stores all the keys of a dict. ``` python def keys_only(flat_dict): - lst = [] - for k, v in flat_dict.items(): - lst.append(k) - return lst + return list(flat_dict.keys()) ``` ``` python
