Question

1. Using this website:
https://en.wikipedia.org/wiki/Greenhouse_gas
Create a named tuple to contain each Gas Concentration data for these columns:
Gas, Pre-1750,Recent, Absolute increase since 1750,Percentage increase since 1750.
Design a class to hold this named tuple and add necessary dunders to support initialization, string
conversion, sorting by a specific column (like 'Recent' for example) and searching.

Expert Solution

Step 1

Algorithm:

Start
Create a list of GreenhouseGasData objects with values for each gas.
Create a GreenhouseGasCollection object and initialize it with the data list.\
Print the GreenhouseGasCollection object using its __repr__ method.
Sort the GreenhouseGasCollection object by the Recent column using the sort_by method.
Print the sorted GreenhouseGasCollection object.
Search for the data of the gas "Carbon dioxide" using the search method.
If the data is found, print it, otherwise print a message saying the data is not found.
Inside the main method, create an object of GreenhouseGasCollection and call the methods by passing necessary data and print the returned value
