You can directly iterate over the keys of a Python dictionary using a for loop and access values with dict_object[key]. You can iterate through a Python dictionary in different ways using the dictionary methods .keys(), .values(), and .items(). You should use .items() to access key-...
A cool way to create dictionaries from sequences of values is to combine them with the built-in zip() function and then call dict() as shown below:Python >>> places = [ ... "Colorado", ... "Chicago", ... "Boston", ... "Minnesota", ... "Milwaukee", ... "...
