Python Dictionary Methods
Python Dictionary is like a map that is used to store data in the form of a key:value pair. Python provides various in-built functions to deal with dictionaries. In this article, we will see a list of all the functions provided by the Python to work with dictionaries.

- get(): This function returns the value for the given key
- keys(): This function returns a view object that displays a list of all the keys in the dictionary in order of insertion
- values(): This function returns a list of all the values available in a given dictionary
- items(): This function returns the list with all dictionary keys with values
Example: Accessing Dictionary Items.

# Python program to demonstrate working# of dictionary copydic = {1:'geeks', 2:'for', 3:'geeks'}print('original: ', dic)# Accessing value for keyprint(dic.get(1))# Accessing keys for the dictionaryprint(dic.keys())# Accessing keys for the dictionaryprint(dic.values())# Printing all the items of the Dictionaryprint(dic.items()) |
original: {1: 'geeks', 2: 'for', 3: 'geeks'}
geeks
dict_keys([1, 2, 3])
dict_values(['geeks', 'for', 'geeks'])
dict_items([(1, 'geeks'), (2, 'for'), (3, 'geeks')])Table of Python Dictionary Methods
| Functions Name | Description |
|---|---|
| clear() | Removes all items from the dictionary |
| copy() | Returns a shallow copy of the dictionary |
| fromkeys() | Creates a dictionary from the given sequence |
| get() | Returns the value for the given key |
| items() | Return the list with all dictionary keys with values |
| keys() | Returns a view object that displays a list of all the keys in the dictionary in order of insertion |
| pop() | Returns and removes the element with the given key |
| popitem() | Returns and removes the key-value pair from the dictionary |
| setdefault() | Returns the value of a key if the key is in the dictionary else inserts the key with a value to the dictionary |
| update() | Updates the dictionary with the elements from another dictionary |
| values() | Returns a list of all the values available in a given dictionary |
