To prevent undue political influence, US Supreme Court justices serve until they either 1) choose to retire, or 2) reach the end of their natural life. The justices.csv file contains information about each US Supreme Court justice appointed in the history of the country. To review, the columns of the file contain: Justice first name Justice last name State the justice is from Name of the president who appointed the justice Year appointed Year the appointment ended The 6th column contains 0 for justices currently serving at the time the data file was compiled. Write a function named three_longest_appts that accepts three arguments: a file name, a beginning year, and an ending year. Return a 2-dimensional array containing the first and last name of the three longest-serving justices appointed between the beginning year and ending year (inclusive). Include in your analysis only those justices whose term has ended (retired or passed away). For full credit, your function should use NumPy concepts and techniques to calculate and return the result without using loops or list comprehensions.
