Question

Identify 5 things that establish a lookup relationship and define them as dictionaries.As an example consider the mapping of State names to their abreviations(e.g. "Maryland" to "MD").You must find a diversity of things and they must have at least 6 keys each. (python 3)

Answer 1

Dictionaries in Python:

Dictionary is a collection of referable entry or a key-value pair in which every key has a value associated with it. The keys in a dictionary must be unique in order for the search to return a unique value as a result of a search query.

We can in general also call the dictionary as a Lookup Table as using the key we look up the value it correspond to in the table defined. The Lookup table or dictionary can be of any thing example being : Abbreviation of a city name and it's Letter code etc.

Things that can form a look up relation :

1. Lookup table of serial number and student .A class of 60 students who get Serial Number for teacher's ease e.g 1-Arjun, 2-Daniel, 3-Brad, 4-Sasy, 5- Anil, 6- Peter

2. Lookup table of whether an eatable item is fruit, snack, main-course, Desserts etc. example "Apple" : "Fruit", "Chowmein" : "Snack", "BeetRoot" : "Vegetable", "Patato": "Vegetable", "Cake": "Deserts", "Wine" : "beverages".

3. Subject code and the subject names usually used in schools/ Colleges e.g ETME : Engneering Mechanics, ETMA : Engneering Mathematics, ETPH : Engneering Physics, ETEC : Engneering Chemistry, ETDS : Engneering Data Structues, ETOS : Engneering OS

4. International Airports Code example Aarhus - AAR, Aberdeen- ABZ, Abilene- ABL, Abu Rudeis- AUE, Agadir-ADA, Aguadilla- BQN

5. Number in representational and numerical form e.g "one" - 1, "Two"- 2, "Three" - 3, "Four" -4, "Five"-5, "six"-6

Python Syntax:

dict1 = {'1':'Arjun', '2':'Daniel', '3':'Brad', '4':'Sasy', '5':'Anil', '6':'Peter'}

dict2 = {'Apple':'Fruit', 'Chowmein':'Snack', 'Beetroot':'Vegetable', 'Patato':'Vegetable', 'Cake':'Desert', 'Wine':'Beverage'}

dict3 = {'ETME':'Engneering Mechanics', 'ETMA':'Engneering Mathematics', 'ETPH':'Engneering Physics', 'ETEC':'Engneering Chemistry', 'ETDS':'Engneering and Data Structure', 'ETOS':'Engneering and OS'}

dict4 = {'AAR':'Arahus', 'ABZ':'Aberdeen', 'ABL':'', 'AUE':'Abu Rudeis', 'ADA':'Agadir', 'BNQ':'Aguadilia'}

dict5 = {'1':'One', '2':'Two', '3':'Three', '4':'Four', '5':'Five', '6':'Six'}

Hope my effort helps your cause.
