- write XPath expressions in an R Notebook that evaluate the following queries; display the results in your R Notebook. What are the titles of all books written by "Galos, Mike"? List the titles and the prices. In what genre is the book with id "bk109". What are the titles of the books that sell for the lowest price? (Use the min aggregation function) List the title and prices of all books in the "Computer" genre. What is the number of all books that cost less than $5? (Use the count aggregation function)Write a function product or sum(num1, num2) that takes two int parameters and returns either their sum or their product, whichever is larger. In the first example below, the sum (17+ 1) is greater than the product (171), so the sum is returned. In the second example, the product (211) is greater than the sum (2+11), so the product is returned For example: Test Result print (product or sum(17, 1)) 18 print (product or sum(2, 11)) 22‘Write a function nesting(), which takes an arbitrary number of parameters, and returns a list containing the arguments. Write another function unnesting(), which takes a list L as the parameter and retums a 1D list. Notice that, you should be able to use loops to solve thisproblem and should not use recursive functions (which we will not cover in this course). ‘Write assertions to test the two functions.For example nesting(1, nesting(2, 3, nesting(4, 5, [6])), [7, 8], 9)unnesting([1, [2, 3, [4, 5, [6]]], [7. 8], 9]) (1, [2, 3, [4, 5, [6]]], [7, 8], 9][1, 2,3, 4, 5, 6, 7, 8 9]
- please code in python MCQ are a very popular form of assessment because they can be automatically graded…and the students can choose an answer at random if they don’t know.The goal of this exercise is to write a function scoreMCQ(attempt, correct), where attempt is a string that contains the answers of the student and correct is a string with the correct answers.The function should return the number of correct answers.Check first that both strings have the same length, otherwise raise an exception.If both strings are empty the score should be 0 of course.To test your code, you can copy paste the following assert statements as your main function:assert(scoreMCQ("","")==0), "First test failed"assert(scoreMCQ("TFTF","TTTT")==2), "Second test failed"assert(scoreMCQ("TTTT","TTTT")==4), "Third test failed"assert(scoreMCQ("CCCC","ABCD")==1), "Fourth test failed"print("All tests succesfull")In this challenge you should repeat a specific given char x times. Create a function that takes a string and a number as arguments and return a string. Examples repeat ("-", 3) repeat ("A", 0) repeat ("c", -1) Notes - ● 1111 11 • Tests can repeat a char 268435440 times, no more. Repeat should be fast maximum execution time : 5 ms. • Total maximum execution time: 3800 ms. • Native repeat is forbidden. • Using of an existing repeat polyfill too (that's not the challenge objective).DateType keeps only the integer representation of the month,day, and year. When a month is wanted in string form, the string iscalculated. An alternate approach would be to add a string field tothe date and calculate and store the string representation in theInitialize function. Which methods would have to bechanged? Would this change make the use of an if statement tofind the appropriate string more or less attractive? Write the code in C++for this if statement.
- Hi there dear expert, Here I have pasted the errors (max 2 allowed, but suffices hopefully), the assignment and my code. It seems the problem is in the function def grade() (and the weights).. it seems to work for all students though but one (error carried along across all functions). Hopefully you can help fix it? Thank you so much in advance. Kind regards Assignment: Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object's attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is…Split blood pressure into systolic and diastolic blood pressure with integer as data type readings and remove the original column. Examine the data and look for predictor columns that are indicator variables, 0 or 1. Convert the data type to Boolean. Using code prepare lists of predictor column names for each data type. Make sure all the predictor columns are included in one and only one list. Print the length of the list of each data type and the sum of the lengths and verify that all predictor variables are accounted for in the lists. Use f-string to align the numbers properly.For each function call below, indicate if it is correct. If a function call is correct, show what is returned. If wrong, explain the mistake and correct it: (a) (list 'x 'y 'z) (b) (cons 'x 'y 'z)
