 Function which accepts a dictionary of key value pairs and returns a new flat list of only the keys.
 
-Uses the .items() function with a for loop on the dictionary to track both the key and value and returns a new list by appending the keys to it. 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
