You can use the IDictionary<TKey,TValue> interface which provides the Add(KeyValuePair<TKey,TValue>) method: IDictionary<int, string> dictionary = new Dictionary<int, string>(); dictionary.Add(new KeyValuePair<int,string>(0,"0")); dictionary.Add(new KeyValuePair<int,string>(1,"1"))...

You create a new key/value pair on a dictionary by assigning a value to that key d = {'key': 'value'} print(d) # {'key': 'value'} d['mynewkey'] = 'mynewvalue' print(d) # {'key': 'value', 'mynewkey': 'mynewvalue'} If the key doesn't exist, it's added and po...
First of all, we have created a dictDat dictionary object and stored two elements. Then, we have used the print() to display the dictionary values. Next, we have used the update() method to add another key along with the value within the previouslyexisting dictionary. Finally, we have us...
Note:This is arguably the most popular method of adding new keys and values to a dictionary. Let's use theupdate()method to add multiple key-value pairs to a dictionary: rainbow = {'red':1}# Update by passing dictionarynew_key_values_dict = {'orange':2,'yellow':3} ...

We create a dictionarymy_dictwith the initial key-value pairs'name': 'Alice'and'age': 30. We add a new row to the dictionary using square brackets[]with the new key'city'and its corresponding value'New York'. Finally, we print the updated dictionary to verify that the new row has be...
The argument must be a dictionary, or an iterable object with key:value pairs.Example Add a color item to the dictionary by using the update() method: thisdict = { "brand": "Ford", "model": "Mustang", "year": 1964 }thisdict.update({"color": "red"}) Try it Yourself » ...
Adds a key/value pair to the ConcurrentDictionary<TKey,TValue> if the key does not already exist. Returns the new value, or the existing value if the key already exists.
该类具有一个value属性,表示数字的值。通过重载__add__方法,实现了Number对象之间以及Number对象与整数之间的相加操作。 在__add__方法中,通过判断other的类型,可以返回不同类型的结果。如果other是Number对象,则返回一个新的Number对象,其值为两个Number对象的值之和。如果other是整数,则返回一个新的Number对象,...
