7.2.1. Data Parsing
Instructions
The provided module data.py contains data on the average annual retail
price of gasoline in the United States from \(1950\) until \(2021\). The data includes
\(4\) values for each year; the year, the real price in dollars per gallon, an
inflation adjustment factor, and the inflation adjusted price in \(2021\) dollars
per gallon. This data is stored as a single list with the values for each year
stored consecutively.
Write a program that imports this data from the provided data.py module
and parses it to calculate the average retail price of gasoline in each decade.
Hint
Consider using list slicing to extract the necessary data.
The results should be displayed as a formatted table. This program should run
without user input.
Sample Output
Ensure your program’s output matches the provided samples exactly.
This includes all characters, white space, and punctuation. In the
samples, user input is highlighted like
this for clarity, but your program should not highlight user
input in this way.
Sample Output
$ python3 data_parsing_login.py
