| dict.fromkeys() | Creates a new dictionary from the given iterable (string, list, set, tuple) as keys and with the specified value. |
| dict.get() | Returns the value of the specified key. |
| dict.items() | Returns a dictionary view object that provides a dynamic view of dictionary elements as a list of key-value pairs. This view object changes when the dictionary changes. |

| dict.update() | Updates the dictionary with the key-value pairs from another dictionary or another iterable such as tuple having key-value pairs. |
| dict.values() | Returns the dictionary view object that provides a dynamic view of all the values in the dictionary. This view object changes when the dictionary changes. |
