TASK $4$: Predicting Data and Plotting

Task $4$ involves predicting temperature changes between the date range of your choice

and a country. You should support your statements by developing appropriate prediction

functions of your choice that calculate these values from the historical data provided.

Provide a brief description of the prediction function used with a justification.

Include a fragment of code with a description of the calculation method with
