The dictionary key<\/strong>\/s are from a Python object or part of an argument in a program.<\/p>\n\n\n\n A Python dictionary is a collection of key-value pairs<\/strong> in which each key corresponds to a value. <\/p>\n\n\n\n A key-value pair’s value may be an integer, text, list, tuple, or even another dictionary.<\/p>\n\n\n\n Additionally, you can use any acceptable Python type for the value of the key-value combination.<\/p>\n\n\n\n Nevertheless, a dictionary key always has its corresponding value as you can see in actual dictionaries.<\/p>\n\n\n\n Python’s keys () function is used to retrieve all of the dictionary’s keys. <\/p>\n\n\n\n The keys must be unique and of an immutable type (string, integer, or tuple with immutable members).<\/p>\n\n\n\n The Python key() function is different from the key that we call or sort from the dictionary. <\/p>\n\n\n\n The function of the key is specifically applicable to returning a key from the dictionary.<\/p>\n\n\n\n However, in some cases, programmers want to sort Python keys in a dictionary which is why we use other functions.<\/p>\n\n\n\n <\/p>\n\n\n\n Sorting is very much needed in Python dictionary for the following reasons:<\/p>\n\n\n\n We have the following ways how to sort Python dictionaries by key and values:<\/p>\n\n\n\n The following are the methods to sort dictionary by key<\/strong>.<\/p>\n\n\n\n In this example, we will try first how to sort the keys in a Python dictionary without displaying its values.<\/p>\n\n\n\n Example:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n The output shows the sorted key from the Python dictionary. To sort it from the Python dictionary, the iterkeys() function is used. <\/p>\n\n\n\n It is presented as The for i in sorted(keylists.keys()):<\/strong><\/mark> is the function that really sorts the key from the Python dictionary. While print(i, end=” “)<\/strong><\/mark> invokes the program to arrange the keys from lowest value to highest and displays the output.<\/p>\n\n\n\n <\/p>\n\n\n\n This example will try to sort the key in the Python dictionary in lexicographic order which will display such as in actual dictionaries.<\/p>\n\n\n\n Example:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n In this example, the program sorts the Python keys (names) in the dictionary order. The outputs then display the keys along with their corresponding values.<\/p>\n\n\n\n OrderedDict<\/strong><\/mark> is a Python subclass under the built-in file “collections”. This subclass has the dict<\/mark> <\/strong>declaration which is understood as a Python dictionary.<\/p>\n\n\n\n The print(OrderedDict(sorted(dict.items())))<\/strong><\/mark> enables the program to sort and display the keys under the subclass.<\/p>\n\n\n\n The next example will try to show you how to sort Python keys and values in a dictionary. This will sort the keys<\/strong> in alphabetical order along with their values.<\/p>\n\n\n\n Example:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n The outputs justify how the function sorts the keys in the Python dictionary. <\/p>\n\n\n\n It does not literally mean alphabetically arranged but the concept is it displays the keys in order (lowest to highest) and their values.<\/p>\n\n\n\n The functions of each program line were the same as the explanation in the first example. <\/p>\n\n\n\n The only difference is their outputs wherein the output of the former example does not include the values.<\/p>\n\n\n\n This example will now show how to sort keys based on their values<\/strong> within the Python dictionary. <\/p>\n\n\n\n Basically, the output should be based on the values of each key in the form of lowest to highest order.<\/p>\n\n\n\n Example:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n As you see in the output, this shows the lowest to highest order of the dictionary based on its values. <\/p>\n\n\n\n When this function is applied to strings, it will show an alphabetical order of strings as an output.<\/p>\n\n\n\n The example below shows how the function works with string as key and integers as their values. <\/p>\n\n\n\n This will sort the Python keys within a dictionary from lowest to highest (alphabetical) based on their values.<\/p>\n\n\n\n This means that the output should display a series of dictionaries with their values arranged from lowest to highest.<\/p>\n\n\n\n Example:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n The output proves that the keys were sorted according to their values. <\/p>\n\n\n\n Their values were arranged from lowest to highest, therefore the keys were placed when their value belonged.<\/p>\n\n\n\n In summary, we covered every detail of the topic of how to do Python sort dictionary by key and values with complete discussion and examples.<\/p>\n\n\n\n Furthermore, you also discovered the important task of how to perform the Python sort dictionary by key and by values. <\/p>\n\n\n\n You may also try the given discussion and tutorials on how to implement sorting Python dictionaries.<\/p>\n\n\n\n But if you want to clarify any of the discussed terms or topics, you can always keep us informed through the comments.<\/p>\n\n\n\n What are dictionary keys?
