1. Ultimate Reference to Python Dictionary Methods
There are certain methods in Python language, that are specified to work with the dictionaries and in this tutorial, we will present all the dictionary functions in alphabetical order. Further, these methods are also called dictionary functions, but these rely only on their parent class. Usually, these methods are built-in in Python programming language and we can use them to work with dictionaries as required. The table below contains all the built-in dictionary methods in this language and serves as an ultimate and up-to-date guide or reference.
2. Search Ultimate Reference For Python Dictionary Methods
Search Python dictionary methods from the below table, which is an ultimate and up-to-date guide or reference, for the developers. Please note that the parameters or arguments of some methods might be optional, so don't worry while writing your Python programs.
2.1. Alphabetical Reference
| Method | Description |
| dict() | This Python method creates a new dictionary. |
| clear() | This Python method clears all the elements from a dictionary. |
| copy() | To create a shallow copy of a dictionary, we use this Python method. |
| formkeys() | To create a new dictionary with specified keys and values, we use this Python method. |
| get() | This Python method returns the of the given key from a dictionary. |
| haskey() | To find if there is a key inside a dictionary, we can use this Python method. |
| items() | This Python method returns a list of dictionary items as key and value pairs. |
| iter() | It returns an iterator over the dictionary keys like the iterkeys() Python method. |
| iteritems() | This Python method returns an iterator over the key-value pairs of the dictionary. |
| iterkeys() | This Python method returns an iterator over the keys of the dictionary. |
| itervalues() | To return an iterator over the values of the dictionary, we can use this Python method. |
| keys() | To get a list of keys of a dictionary, we utilize this Python method. |
| pop() | This Python method removes an element at a given key index in a dictionary and returns it. |
| popitem() | To remove the last inserted key-value pair from a dictionary, we use this Python method. |
| setdefault() | This Python method sets the default value of a key and returns it in a dictionary. |
| update() | To update the dictionary with a specified key-value pair, we can use this Python method. |
| values() | This Python method returns a list of all the values of a dictionary. |
| viewitems() | This Python method returns a new view of the dictionary items i.e. key-value pairs. |
| viewkeys() | To get a new view of the keys of the dictionary, we use this Python method. |
| viewvalues() | To get a new view of the values of the dictionary, we use this Python method. |
3. Dynamically Get Python Dictionary Methods
Python has a variety of methods that can work with dictionaries, and luckily you can avail the up-to-date list by the help of below script.
Get All Dictionary Methods
# Get the list of dictionary methods
dictionary_methods = [
method
for method in dir(dict)
if callable(getattr(dict, method))
and not method.startswith('__')
]
# Print the list of dictionary methods
print(dictionary_methods)
Note:
Importantly, it is important to note that these methods are different from those of built-in Python functions, so make sure to keep this in mind.
