Question

What is Dictionaries? how are dictionaries different from lists?
​

Answer 1

Answer:

Lists are ordered sets of objects, whereas dictionaries are unordered sets. But the main difference is that items in dictionaries are accessed via keys and not via their position. A dictionary is an associative array (also known as hashes). Any key of the dictionary is associated (or mapped) to a value.
