Task 1: The InstantRide received some traffic violation tickets from the government. The Legal team of InstantRide requires the travel information of the respective drivers along with corresponding Driving License IDs to proceed further. In addition, the team wants to include the drivers without travel information in the system yet for the completion of driver list. Therefore, you need to return DRIVER_FIRST_NAME, DRIVER_LAST_NAME, DRIVER_DRIVING_LICENSE_ID, TRAVEL_START_TIME, TRAVEL_END_TIME information from the DRIVERS and TRAVELS data connected by LEFT JOIN. Task: Query all drivers with and without travel data. (SQL Database Test)

Task 4: The InstantRide User Satisfaction team is a core team for InstantRide, and they focus on increasing the customer satisfaction. They want to learn the travel time for each ride in the system. You need to return the USER_ID, and the TRAVEL_TIME column which is calculated using the TIMEDIFF function on the TRAVEL_END_TIME and the TRAVEL_START_TIME.
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.
(1) for each Customer (e.g., customer C), display all other customers who have higher salary than this Customer (e.g., customer C). (use inner join, display each customer’s ID, name, and all higher salaries, you don’t need to display information about the customers who have higher salary.) (2) for each Customer (e.g., customer C), display all other customers who have higher salary and are younger than this Customer (e.g., customer C).
