Python sort dictionary in Python can be done in various ways. This post will discover what a dictionary is and why it is necessary to categorize dictionaries. What are the ways to sort a dictionary in Python? Later, we’ll look at how to sort the dictionary by value and keys, an example, and the resulting output and can get python programming help. So, let’s get this started! What makes learning so important? There is a simple explanation: language improvements lead to new libraries and tools. For a programmer to stay on top of these changes and become successful, knowing how to learn is crucial.
The consistency of your learning is crucial when you’re learning a new language. Every day, you should commit to learning a new language. Muscle memory plays an important role in programming, as hard as it may seem. If your code every day, you will develop it. It may seem overwhelming at first, but you can begin with 25 minutes each day and progress from there.
 The answer is yes! Taking notes by hand is proven to be the best method of retaining information for the long run, according to research. Â
You can plan your code before moving to the computer by writing by hand once you start working on small projects and programs. If you know which functions and classes you will need and how they will interact in advance, you can save a great deal of time.

What is Dictionary?
A dictionary in python is a data structure used for multiple purposes. Unlike any other data type, a dictionary is an ordered collection of data elements stored like a map. Dictionary holds data as a key-value pair, allowing for more efficient data collecting. Remember that the dictionary keys do not allow for repetition. As a result, dictionary objects are sorted, editable, and don’t allow duplicates.
Applying the appropriate key name, we can obtain data objects from a dictionary. Between the curly braces(), we may specify the dictionary as a comma-separated list of key-value pairs. Dictionary holds data as a key-value pair, allowing for more efficient data collecting. Remember that the dictionary keys do not allow for repetition. As a result, dictionary objects are sorted, editable, and don’t allow duplicates.
Between the appropriate key and value in the dictionary, a colon(:)) separates them. Keep in mind that the key must be a single element, whereas the value can be any sort of data.
Why We Need for Sorting in Dictionary
When dealing with a significant amount of data, data sorting is crucial, and it might be challenging to produce the desired output fast and efficiently when the data collection is extensive. In such circumstances, we can simplify the complexity of data collecting by sorting it into numerical or alphabetical order to obtain a quick result.
Consider your mobile phonebook, for example. The people’s contact information is saved with their names as a key, with no names repeated, and they are grouped in alphabetical order for efficient searching.
As a result, when you want to find a person’s contact information with a specific name, you go to the first letter of the name in your phonebook and save time and effort by reading through each contact detail. By this example, we may conclude that sorting the dictionary is necessary for programming and crucial in our daily lives.
Python Sort Dictionary by Key
We can sort the dictionary using the keys component in addition to utilizing the values component. By this example, we may conclude that sorting the dictionary is necessary for programming and crucial in our daily lives.
There are three methods for sorting the dictionary using the keys listed below.
Using LoopÂ
Using the keys()Python and a loop, we can sort the dictionary in Python. The keys() method is used to extract the keys from the dictionary, sorted using the for a loop. As we show in the following example, we obtain a sorted dictionary as the output:
Sorting using sorted() MethodÂ
 As illustrated in the example below, we call the sorted method for the given dictionary and then sort it using the for loop for the given keys:
Sorting Using items() Method
With the help of the items() method, we can sort the dictionary by keys. We use the dictionary after calling the dictionary for the sorted() method. items() can be used to sort the dictionary by keys, as shown in the example below:
In Python, sort a dictionary by value
Because we all know that dictionaries include key and value pairs, there are three approaches for sorting the dictionary using the value component. Let’s take a closer look at each of these three methods
Using for Loop
To sort the dictionary in Python using value, we can use the sorted() method and the for a loop. In the technique, we first build a list of dictionary keys and then use the sorted() method to sort the list of keys in a loop. As seen in the example below, the output will be a sorted dictionary:
By Using Lambda Function
To sort a dictionary by value in Python in a preset order, use the sorted() method and the lambda function. The lambda function in Python provides an anonymous function that aids in code optimization. The lambda function will have the following syntax.
By Using dictionary.items() Method
In this approach, we’ll sort the dictionary with items() methods and the sorted() method in Python. The method sorts the dictionary by its values and returns the sorted dictionary as follows:
- This tutorial will be using Python 3, the latest major version of Python. It is still quite popular, even though it has only been updated with security updates.
Â
- The use of an Integrated Development Environment, such as Thonny, Pycharm, Netbeans, or Eclipse, provides a more convenient way to manage Python files, especially when handling large collections.
