But, it works with only one key/value at a time. If we need to update multiple key-value pairs in the dictionary, we have to use the update() function. The update() function can also add multiple dictionaries into one single dictionary. The following code example shows how we can ...
Theupdate()method adds a new element to an existing dictionary: dictionary_name.update({key:value})Copy The method also accepts multiple key-value pairs. To use theupdate()method, see the example below: my_dictionary = { "one": 1, ...
