In this case, you use the dict() constructor to generate a new dictionary from the data that map() returns. In the second and third calls to map(), you wrap apply_discount() in a lambda function so that you can provide a different discount value to apply_discount(). This is a ...
First, we will usedict.values()method, which is used to extract all the values from the dictionary like this:dict_values([val1, val2….]). To convert it into a list, we will use the list constructor. Syntax list(dict_name.values()) values():Make sure that you are using this meth...

If you have a container as a value, and you want to retrieve a nested value—that is, something from within the container—you can either access it directly with indexing (if supported), or by using an interstitial assignment: example_values["another_dict"]["Blade Runner"] # yields 1982...
