I have a program that asks for queries. It is based on a CSV file with three columns for a person's name, city, and height. The print statement for City_list gives it a blank. The problem I'm running into is that if I insert a city that isn't in the CSV file, it ends and doesn't transition to other cities. When I do put in the city that is in the list, it prints out the indexes from the file. How can this be revised to ignore off-list cities and work with in-list cities?

10 mplete out of question Complete the transform_2d_list() function that takes a single two-dimensional list as a parameter called a_2d_list. The parameter list has m items, where each item is a list with n items. The function returns a new two-dimensional list, where the first item is a list containing all of the first items in the list items of the original list, and the second item is a list containing all of the second items in the list items of the original list and so on. In other words, the two- dimensional list that is returned will have n items, where each item is a list with m items. You can assume that both m and n are at least 1. Some examples of the function being called are shown below. For example: Test a_2d_list = [[1]] print (transform_2d_list (a_2d_list)) a_2d_list = [['a'], ['b']] print (transform_2d_list (a_2d_list)) a_2d_list = [[1, 2], [3, 4]] print(transform 3d lint( Result [[1]] [['a', 'b']] [[1, 3], [2, 4]]

Write a procedure called check_workday(check_day). The procedure should accept a single word as a parameter. You have been given a list called work_days. The list contains a couple of days that are defined as workdays for this problem. You are required to: check to see if the day passed to the procedure is a workday. If it is a workday print The name of the day, with the following statement on the same line: " is a workday" (see the example outputs) When the day is a Sunday, display the following statement on the next line: "The fee is double because it is Sunday." NB: Only write the procedure. Do not call it. Please refer to the examples below for further clarity. For example: Test Result check_workday("Monday") Monday is a workday check_workday("Sunday") Sunday is a workday The fee is double because it is Sunday. check_workday("Thursday") Thursday is a workday
