Switch Case in Python

Problem:

This is for my understanding and memory I  need to write about the Python way of writing switch case. One such way is writing the if elif and else construct but the other way as mentioned in the some of the code I have seen as is to use the dictionary as key value pair and match the key of the dictionary key as a case value and return the same from the dictionary.

Solution:

The solution below explains the logic for the same and do keep in mind why this is working out because

  • For the dictionary a = {key:value}  the expression a[key]  and {key:value}[key] are same and will give out value
