Python - Dictionary, Basic Computer Science

Assignment Help:
A dictionary is variable and is one more container type that can store any number of Python objects, counting other container types.
Dictionaries consist of pairs (identified items) of keys and their equivalent values.
Python dictionaries are also recognized as associative arrays or hash tables. The common syntax of a dictionary is as shown:
dict = {''Alice'': ''2341'', ''Beth'': ''9102'', ''Cecil'': ''3258''}
You can generate dictionary in the following method additionally:
dict1 = { ''abc'': 456 };
dict2 = { ''abc'': 123, 98.6: 37 };
Each key is divided from its value by a colon (:), the items are divided by commas, and the entire thing is enclosed in curly braces. An empty dictionary with no any items is written with simply two curly braces, approximating this: {}.
Keys are exclusive within a dictionary while values may not be. The values of a dictionary can be of any type, but the keys must be of an unchallengeable data type for example strings, numbers, or tuples.
