Note: for more information, refer to python dictionary. defaultdict. defaultdict is a container like dictionaries present in the module collections. defaultdict is a sub class of the dictionary class that returns a dictionary like object. Creating python defaultdict. to create a defaultdict, we need to import the defaultdict class from the collections module. to do that, we can use the following line of code. example of importing the defaultdict in python. from collections import defaultdict. the defaultdict takes a function as an argument to return values for missing keys. Approach: import the defaultdict from collections using the import keyword. create a dictionary by passing the lambda function as an argument to defaultdict. give some random keys and values for the above dictionary. pass the above keys to missing () function and print it. the exit of the program. For example, we can assign a new key value pair to the dictionary: # assigning a value to a provided key from collections import defaultdict default = defaultdict () default [ 'name'] = 'nik' print (default) # returns: defaultdict (none, {'name': 'nik'}) in this section, you learned how to create a defaultdict in python and how to add key value.

Python defaultdict is used to deal with missing keys. in this lesson, you’ll learn how to use the python defaultdict to deal with missing keys. you already know that when you establish a new defaultdict, you must specify a new default value type. when attempting to retrieve a missing key, this allows us to manage missing data. Example #. collections.defaultdict (default factory) returns a subclass of dict that has a default value for missing keys. the argument should be a function that returns the default value when called with no arguments. if there is nothing passed, it defaults to none. In the code example, we imported the collections module and used the dir () function to print all objects of the module. we can see that counter, defaultdict, ordereddict, and namedtuple are the objects of the collections module. let us see each of then now: 1. counter in python. it is used to count hashable objects.
