For printing the keys and values, we can either iterate through the dictionary one by one and print all key-value pairs or we can print all keys or values at one go. Python also offers enumerate () with helps to iterate over all kinds of containers, be it dictionary or a list. To learn more about dictionary, please visit Python Dictionary.

Python Dictionary values() The values() method returns a view object that displays a list of all the values in the dictionary.

In Python, a dictionary is an unordered collection of items. Python – Concatenate Dictionary string values. How the values of the nested dictionary can be printed by using get() method is shown in this example. Let’s discuss string concatenation of like key values and ways to solve it in this article. Dictionaries aren't sequences, so they can't be indexed by a range of numbers, rather, they're indexed by a series of keys. The view object will reflect any changes done to the dictionary, see example below. The following example shows the usage of values() method.

In a list, the indices have to be integers; in a dictionary they can be (almost) any type. This can be extended to any operation to be performed. The sorted() method along with Python operator.itemgetter() method can be used to sort a dictionary by value in Python.. Python operator module has various in-built functions to manipulate the data and values. However, this behavior may vary across different Python versions, and it depends on the dictionary’s history of insertions and deletions. Syntax.

For example: dictionary = {'key' : 'value', 'key_2': 'value_2'} Here, dictionary has a key:value pair enclosed within curly brackets {}. Following is the syntax for values() method − dict.values() Parameters.

When one or more dictionaries are declared inside another dictionary then it is called a nested dictionary or dictionaries of the dictionary. In Python 3.6 and beyond, the keys and values of a dictionary are iterated over in the same order in which they were created.
