Three variables , x, y and z, supposedly hold strings of digits, suitable for converting to integers. write code that converts these to integers and print the sum of these three integers. however, if any variable has a value that cannot be converted to an integer, print out, the string "bad value(s) in: " followed by the names of the variables that have bad values (separated by spaces, in alphabetically ascending order).for example, if the values of x, y and z were respectively "3", "9", "2" then the number 14 would be printed; but if the values were "abc", "15", "boo" then the output would be: bad value(s) in: x zthis is what i have so far: try: print(int(x)+int(y)+int(z))except valueerror: if x=valueerror: print("bad value(s) in: ", x) elif y=valueerror: print("bad value(s) in: ", y) elif z=valueerror: print("bad value(s) in: ", z)python3 .

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.
