Get

The get method in Python helps you to retrieve the value for the specified key if key is present in a given dictionary. Solution: Let’s have a look at the solution to visualize the usage of the get method to extract values from a dictionary. Definition and Usage The get method returns the value of the item with the specified key. The values of all nested dictionaries are printed by using loop or keys in the above examples. Get method can be used in python to read the values of any dictionary. How the values of the nested dictionary can be printed by using get method is shown in this example. # Create a nested dictionary. In this post, we will discuss dict’s setdefault and getdefault in Python. These are two handy programming idioms in Python. When we get the value from a dict, if the key does not exist in dict, a None will be returned.

The dict.values() method 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.

Syntax:

Parameters:

No parameters

Return Value:

Returns a view object with the list of all values in the dictionary.

The following example demonstrates the dict.values() method.

The following example shows the working of dict.values() when the dictionary is updated.

In the above example, the values() function does not return the list of values but returns a view object of the values. Any change in the dictionary is reflected in the view object.

Python – Print Dictionary

To print dictionary items: key:value pairs, keys, or values, you can use an iterator for the corresponding key:value pairs, keys, or values, using dict.items(), dict.keys(), or dict.values() respectively and call print() function.

In this tutorial, we will go through example programs, to print dictionary as a single string, print dictionary key:value pairs individually, print dictionary keys, and print dictionary values.

Print Dictionary as a Single String

To print whole Dictionary contents, call print() function with dictionary passed as argument. print() converts the dictionary into a single string literal and prints to the standard console output.

In the following program, we shall initialize a dictionary and print the whole dictionary.

Print Dictionary Key:Value Pairs

To print Dictionary key:value pairs, use a for loop to traverse through the key:value pairs, and use print statement to print them. dict.items() returns the iterator for the key:value pairs and returns key, value during each iteration.

In the following program, we shall initialize a dictionary and print the dictionary’s key:value pairs using a Python For Loop.

Print Dictionary Keys

To print Dictionary keys, use a for loop to traverse through the dictionary keys using dict.keys() iterator, and call print() function.

In the following program, we shall initialize a dictionary and print the dictionary’s keys using a Python For Loop.

Print Dictionary Values

To print Dictionary values, use a for loop to traverse through the dictionary values using dict.values() iterator, and call print() function.

Python Dict Getattr

In the following program, we shall initialize a dictionary and print the dictionary’s values using a Python For Loop.

Summary

Python Dict Get Values

In this tutorial of Python Examples, we learned how to print Dictionary, its key:value pairs, its keys or its values.
