<\/span><\/h2>\n\nTo append a value to a dictionary in Python, you need to specify the key and assign the desired value to it. If the key already exists, the value will be updated; otherwise, a new key-value pair will be added.<\/p>\n
The syntax to append a value to a dictionary in Python is as follows:<\/b><\/p>\n
“`python
\ndictionary_name[key] = value
\n“`<\/p>\n
Now, let’s see some examples to understand how this works.<\/p>\n
Example 1:<\/b>
\n“`python
\n# Creating an empty dictionary
\nmy_dict = {}<\/p>\n
# Appending a value to the dictionary
\nmy_dict[“key1”] = “value1”<\/p>\n
print(my_dict)
\n“`<\/p>\n
Output:<\/b>
\n“`
\n{‘key1’: ‘value1’}
\n“`<\/p>\n
In this example, we start with an empty dictionary and append the key-value pair “key1″:”value1” to it. The output displays the updated dictionary.<\/p>\n
Example 2:<\/b>
\n“`python
\n# Creating a dictionary with initial values
\nmy_dict = {“key1”: “value1”, “key2”: “value2”}<\/p>\n
# Appending a value to the dictionary
\nmy_dict[“key3”] = “value3”<\/p>\n
print(my_dict)
\n“`<\/p>\n
Output:<\/b>
\n“`
\n{‘key1’: ‘value1’, ‘key2’: ‘value2’, ‘key3’: ‘value3’}
\n“`<\/p>\n
In this example, we have a pre-existing dictionary with two key-value pairs. We append a new key-value pair “key3″:”value3” to the dictionary and display the updated dictionary.<\/p>\n
