Algorithm and explanation
- Initialize the sample values used to create a dictionary comprehension.
- Process the data step by step using Dictionary comprehension.
- Display the result for create a dictionary comprehension and compare it with the documented sample output.
This example of create a dictionary comprehension processes the sample values in a controlled iteration. It demonstrates Dictionary comprehension and prints a deterministic result that can be checked against the sample output.
