For this portion of the lab design the solution in the following manner: Create a table using a two-dimensional list that stores a Fahrenheit temperature and the equivalent Celsius temperature. Use the following range of Fahrenheit temperatures:Starting at -10 through 100 in increments of 10. Thus, the Fahrenheit temperatures will be:-10, 0, 10, 20, 30, 40, 50…and so on.Display the contents of the list.Similarly create tables/lists for the following, starting at 0 through 100 in increments of 10:Miles to kilometersGallons to litersPounds to kilogramsInches to centimetersDisplay the contents of each listSave the program as firstname_lastname_Lab7a.py where you will replace firstname and lastname with your actual first and last name.
