- Python: numpy def serial_numbers(num_players):"""QUESTION 2- You are going to assign each player a serial number in the game.- In order to make the players feel that the game is very popular with a large player base,you don't want the serial numbers to be consecutive. - Instead, the serial numbers of the players must be equally spaced, starting from 1 and going all the way up to 100 (inclusive).- Given the number of players in the system, return a 1D numpy array of the serial numbers for the players.- THIS MUST BE DONE IN ONE LINEArgs:num_players (int)Returns:np.array>> serial_numbers(10)array([1. 12. 23. 34. 45. 56. 67. 78. 89. 100.])>> serial_numbers(12)array([1. 10. 19. 28. 37. 46. 55. 64. 73. 82. 91. 100.])""" # print(serial_numbers(10)) # print(serial_numbers(12))arrow_forwardProgram Unit Score Calculator Console App Write a Python Console Application program that allows the user to enter the marks for different assessments in a unit, and computes the total mark and grade for the unit. Here is the program logic specification: There are six assessment activities Quiz1, Quiz2, Quiz3, Quiz4, Lab Journal, Major Assignment and Final Exam. The four quizzes are worth 5 marks each, the Lab Journal is worth 10 marks, the Major Assignment is worth 30 marks and the Final Exam is worth 40 marks. The algorithm for computing the total mark for the unit is: Total Mark = Quiz1+Quiz2+Quiz3+Quiz4+Major Assignment+ Lab Journal + Final Exam The following screenshot shows a successful test run:arrow_forwardA complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1) The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas: a + bi + c + di = (a+c) + (b+d)i (addition) a + bi − (c + di) = (a−c) + (b−d)i (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication) (a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division) You can obtain the Absolute Value for a complex number using the following formula: |a + bi| = √(a2 + b2) A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.
