Dictionaries are another fundamental data structure in Python. A dictionary is similar to a list in that it is comprised of a series of data elements. One important difference is that a dictionary uses "keys" instead of indices to access elements. The keys can be strings or other data types. While a list is a sequence, the elements in a dictionary don't have any intrinsic order. A dictionary is a good choice to collect different types of data.
