Dictionary Methods
Dictionary methods in python
Dictionary methods refer to the built-in functions and operations that can be performed on dictionaries, which are a type of data structure in Python. Some of the common methods include adding and deleting elements, updating values, accessing keys and values, looping through dictionaries, and merging dictionaries. These methods provide a flexible and efficient way to manipulate and work with data in a dictionary format.
dictionary methods in Python their uses
- clear(): Removes all the elements from the dictionary.
- copy(): Returns a shallow copy of the dictionary.
- fromkeys(seq[, value]): Returns a new dictionary with keys from seq and values set to value.
- get(key[, default]): Returns the value of the key. If the key is not found, it returns the default value.
- items(): Returns a view object that contains the key-value pairs of the dictionary.
- keys(): Returns a view object that contains the keys of the dictionary.
- pop(key[, default]): Removes the key and returns its value. If the key is not found, it returns the default value.
- popitem(): Removes and returns an arbitrary key-value pair from the dictionary.
- setdefault(key[, default]): Returns the value of the key. If the key is not found, it inserts the key with the default value.
- update([other]): Updates the dictionary with the key-value pairs from other.
- values(): Returns a view object that contains the values of the dictionary.
These methods provide powerful tools to manipulate and work with data in a dictionary format, making it easier to perform operations such as updating, deleting, and retrieving data from a dictionary. By utilizing these methods, developers can create efficient and reliable programs that leverage the capabilities of Python dictionaries
here are examples of each method with explanations:
- clear(): Removes all the elements from the dictionary.
# Example:
my_dict = {1: 'one', 2: 'two', 3: 'three'}
my_dict.clear()
print(my_dict) # Output: {}
- copy(): Returns a shallow copy of the dictionary.
# Example:
my_dict = {1: 'one', 2: 'two', 3: 'three'}
new_dict = my_dict.copy()
print(new_dict) # Output: {1: 'one', 2: 'two', 3: 'three'}
- fromkeys(seq[, value]): Returns a new dictionary with keys from seq and values set to value.

print(my_dict) # Output: {'a': 0, 'b': 0, 'c': 0}
- get(key[, default]): Returns the value of the key. If the key is not found, it returns the default value.
# Example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
print(my_dict.get('a', 0)) # Output: 1
print(my_dict.get('d', 0)) # Output: 0
- items(): Returns a view object that contains the key-value pairs of the dictionary.
# Example:

- keys(): Returns a view object that contains the keys of the dictionary.
# Example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
print(my_dict.keys()) # Output: dict_keys(['a', 'b', 'c'])
- pop(key[, default]): Removes the key and returns its value. If the key is not found, it returns the default value.
# Example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
print(my_dict.pop('a', 0)) # Output: 1
print(my_dict.pop('d', 0)) # Output: 0
- popitem(): Removes and returns an arbitrary key-value pair from the dictionary.
# Example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
print(my_dict.popitem()) # Output: ('c', 3)

- in: Returns True if the key exists in the dictionary.
# Example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
print('a' in my_dict) # Output: True
print('d' in my_dict) # Output: False
- del: Removes a key-value pair from the dictionary.
# Example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
del my_dict['a']
print(my_dict) # Output: {'b': 2, 'c': 3}
- clear: Removes all key-value pairs from the dictionary.
# Example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
my_dict.clear()
print(my_dict) # Output: {}
- keys, values and items can be converted into lists.
# Example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
print(list(my_dict.keys())) # Output: ['a', 'b', 'c']
print(list(my_dict.values())) # Output: [1, 2, 3]
print(list(my_dict.items())) # Output: [('a', 1), ('b', 2), ('c', 3)]
