Python - remove dictionary items
0 points
In this article, we would like to show you how to remove dictionary items in Python.
Quick solution:
xxxxxxxxxx1
my_dict = {2
"id": 1,3
"name": "Tom",4
"age": 255
}6
7
my_dict.pop("age")
In this example, we use pop() method that removes the item with specified key name.
xxxxxxxxxx1
my_dict = {2
"id": 1,3
"name": "Tom",4
"age": 255
}6
7
my_dict.pop("age")8
9
print(my_dict.items()) # [('id', 1), ('name', 'Tom')]Output:
xxxxxxxxxx1
dict_items([('id', 1), ('name', 'Tom')])In this example, we use popitem() method that removes the last inserted item.
xxxxxxxxxx1
my_dict = {2
"id": 1,3
"name": "Tom",4
"age": 255
}6
7
my_dict.popitem()8
9
print(my_dict.items()) # [('id', 1), ('name', 'Tom')]Output:
xxxxxxxxxx1
dict_items([('id', 1), ('name', 'Tom')])Note:
In versions earlier than Python 3.7 the
popitem()method removes random item instead.
In this example, we use del keyword that removes item with the specified key name.
xxxxxxxxxx1
my_dict = {2
"id": 1,3
"name": "Tom",4
"age": 255
}6
7
del my_dict["age"]8
9
print(my_dict.items()) # [('id', 1), ('name', 'Tom')]Output:
xxxxxxxxxx1
dict_items([('id', 1), ('name', 'Tom')])In this example, we use clear() method to empty the dictionary.
xxxxxxxxxx1
my_dict = {2
"id": 1,3
"name": "Tom",4
"age": 255
}6
7
my_dict.clear()8
9
print(my_dict.items()) # []Output:
xxxxxxxxxx1
dict_items([])
