<\/span><\/h3>\n\nTo add a new value to a key in a dictionary in Python, you can simply access the key in the dictionary and assign the new value to it. Here is an example:<\/strong><\/p>\n“`python
\nmy_dict = {‘apple’: 5, ‘banana’: 3}
\nmy_dict[‘apple’] = 7
\nprint(my_dict)
\n“`<\/p>\n
In this example, we first define a dictionary called `my_dict` with key-value pairs. Then, we access the key ‘apple’ in the dictionary and assign a new value of 7 to it. Finally, we print the updated dictionary, which now has the key ‘apple’ with a value of 7.<\/p>\n
