Yes3Dictionary method, which returns a list-like value, corresponding to the dictionary's key, value, and key-Value pairs:Keys ()、VALUES ()AndItems ()。 The values returned by these methods are not real lists, they cannot be modified, noAppend () method. However, these data types ( dict_keys,dict_values, and Dict_items, respectively ) can be used for a for loop. To see how these methods work, enter the following code in the interactive environment: Python
