The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.
For this portion of the lab, you will reuse the program you wrote in Lab 3A. Redesign this solution so that some portions of the code are repeated. In lab 3 you validated input to ensure that the user entered inputs within certain values. If the user entered an invalid value, the program terminated. Now you will add a loop such that the user gets three changes to enter a valid value. If the user enters an invalid value more than three times in a row, the program should issue an error message and terminate. Save the program as firstname_lastname_Lab4a.py where you will replace firstname and lastname with your actual first and last name. Test all conditions prior to submitting. If the user enters an invalid value, then the program will issue an error message and terminate immediately. (Do NOT accept further data).

Recall the following segment of Java code for computing the set-difference of two given arrays (note that the lines have been numbered for the sake of reference): (1) int[] a, b; (2) (3) (4) (5) (6) (7) (8) (9) (10) count=0; (11) for (int i=0; i<=a.length-1; i++) { (12) (13) (14) (15) (16) (17) (18) (19) (20) (21) (22) (23) } (24) (25) int[] ans = new int[count]; (26) for (int i=0; i<-count-1; count++) (27) // Input the arrays a and b here int[] tempAns; int count,j; boolean found; tempAns = new int[a.length]; found = false; j-e; while (j<-b.length-1 && !found) { if (a[i]==b[j]) found = true; j+; } if (!found) { tempAns[count]=a[i]; count++; } ans[i] = tempAns[i]; Suppose we want to modify the above code to compute the set union of the arrays a and b, i.e., the set of all elements that are in either a or b. Which of the following changes would accomplish that?
Consider the following code: j = 3 while j < 10 : print("J has value ", j) After how many times does the loop stop?
Chapter 5 Loops and Files 6. Distance Traveled The distance a vehicle travels can be calculated as follows: distance = speed time For example, if a train travels 40 miles per hour for 3 hours, the distance traveled is 120 miles. Write a program that asks the user for the speed of a vehicle (in miles per hour) and how many hours it has traveled. The program should then use a loop to display the distance the vehicle has traveled for each hour of that time period. Here is an example of the output: What is the speed of the vehicle in mph? 40 How many hours has it traveled? 3 Hour Distance Traveled 40 80 3. 120 Iuput Validation: Do not accept a negative number for speed and do not accept any value less than 1 for time traveled.
Make the following modifications for the solution above: name the output/input file "myRandomNumbers.txt" use a loop to output 17 random numbers to the file after creating the file, close it open the file for input and read the contents and then total the numbers in the file determine the average of the numbers in the file determine the highest and lowest numbers in the file DO NOT USE PYTHON BUILTIN FUNCTIONS TO CALCULATE THE AVERAGE OR THE HIGHEST AND LOWEST NUMBERS an expected number of modules/functions would be in the 5-8 range Display your results: the numbers generated on a single horizontal line the calculated total and average the highest and lowest number in the file Be sure to use clear prompts/labeling for input and output.
Case - I: Playing with Digits Write a program which reads input integers from input file which consists a series of numbers where each integer contains only of the digits from 0 to 9. SO 1. Count total digits in the number SO 2. Count & Print the even digits SO 3. Count & Print Odd Digits SO 4. Showing how many times each digit appears in the integer. Specifically if a is an integer is countTotalDigits (a):// Returns total digits in integer // Function to count & print even digitS countEvens (a) ; countodds (a) ; // Function to count & print odd digits countDigits (a) ; // Function to count & print digits with stars

Using a Counter-Controlled whileLoop Summary In this lab, you use a counter-controlled while loop in a Java program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements. Instructions Ensure the file named Multiply.java is open. Write a counter-controlled while loop that uses the loop control variable to take on the values 0 through 10. Remember to initialize the loop control variable before the program enters the loop. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop. Execute the program by clicking Run. Record the output of this program.
