Please use python • generate_number(pct_per_digit): Takes one float as input. Returns a random number that isconstructed as follows. First, use the function above to get a random number. This number willcorrespond to the length (number of digits) that the number generated by this function should have.For example, if that function returns 3, then this function should generate and return a randomnumber with three digits. Note that the first digit of the number should never be 0 (but furtherdigits, if any, can be 0).Note: As there are different ways to write this function, we will not be checking the specific examplesbelow but only that the numbers returned from the function (given a length of n as returned fromthe function above) are equally distributed in the range 10'n – 1) to (10") – 1. E.g., for n=5, from10,000 to 99,999. That is, if we were to run your function many times, then any number in thatrange should be equally likely to be generated.->>> random. seed(1337)>>> generate_number(0)>>> random. seed(9002)>>> generate_number(0.5)41700

Python can generate such random numbers by using the random module.

Write two functions using the following headers:int generate01()void printMatrix(int n)The first function generates and returns a random number either 0 or 1.The second function prints an n-by-n matrix. Each element of the matrix is using the number generated by thefirst function.Write a test program that prompts the user to enter n and uses printMatrix to display an n-by-n matrix. Hereis a sample run:Enter n: 30 1 00 0 10 0 0
def cuberoot(n): """Computes the cube root of float n by fixpoint iteration""" cuberoot: This function should use fixed-point iteration to return the cube root of a given n (positive or negative floating point number). Your implementation should ideally return a precise approximation, but must be correct to at least eight significant digits and must use fixpoint iteration.
In statistics the mode of a set of values is the value that occurs most often. Write a program that determines how many pieces of pie most people eat in a year. Set up an integer array that can hold responses from 30 people. For each person, enter the number of pieces they say they eat in a year. Then write a function that ﬁnds the mode of these 30 values. This will be the number of pie slices eaten by the most people. The function that ﬁnds and returns the mode should accept two arguments, an array of integers, and a value indicating how many elements are in the array.
Cyclops numbersdef is_cyclops(n):A nonnegative integer is said to be a cyclops number if it consists of an odd number of digits so that the middle (more poetically, the “eye”) digit is a zero, and all other digits of that number are nonzero. This function should determine whether its parameter integer n is a cyclops number, and return either True or False accordingly n Expected result 0 True 101 True 98053 True 777888999 False 1056 False 675409820 False

initialise a variable named Min and set its value equal to first item of array. start a for loop to iterate through every element of marks array. check if item<Min. if 4 is true: set Min = item, else continue after the loop will finish, Min variable will have lowest marks For total marks for all the students. initialise a variable named Sum and set its value equal to zero. start a for loop to iterate through every element of marks array. for every iteration, do sum = sum+item after the loop will finish, sum variable will have total marks of all students The overall average. initialise a variable named Sum and set its value equal to zero. initialise another variable count =0. start a for loop to iterate through every element of marks array. for every iteration, do sum = sum+item, and increase count by 1. after the loop will finish, sum variable will have total marks of all students and count will have total count of marks. 5. to calculate average, do average = sum/count.

Complete the get_sum_of_evens (lower_bound, upper_bound) function that takes two integer parameters, lower bound and upper bound. The function returns the sum of all the even numbers between the two bounds, both included, passed to the function. You can assume that lower bound will always be smaller than or equal to upper_bound. For example: Test result get sum_of_evens (2, 4) print("The sum of all even numbers are:", result) print (get_sum_of_evens (9, 17)) Result The sum of all even numbers are: 6 52
Q2: In this question, you will write a Python function to compute the Hadamard product of two matrices. The Hadamard product is the "component-wise" product of two matrices. That is, each entry of the product matrix is equal to the product of its corresponding entries of the input matrices. Here is an example: a11 a12 a21 a22 a23 a31 a13 SH a32 033 A b11 b12 b13 b21 b22 b23 b31 b32 b33. B = [an bu a21 b21 a31 b31 a12 b12 a22 b22 a32 b32 a13 b13 a23 b23 a33 b33. Hadamard product of A and B Write a Python function to compute the Hadamard product of two matrices as follows. a) The inputs to the function are two matrices. b) The function should check whether the two matrices have the same size. If not, it should print "The input matrices are not of the same size". c) If two matrices are of the same size, the function computes the Hadamard product and returns the answer. Use for loops to compute the Hadamard product.
multiplyMatrices(int[][], int[][]) This is a public static function that takes two 2D array's (int[][]) also known as matrices and returns the dot product of the two matrices. In other words this function is suppose to multiply the matrices it receives and return the product. For more information on how to multipy a matrices please recieve this tutorial. You can expect the number of columns in the first matrix to be the same number of rows in the second matrix.
Sum of two squares def sum_of_two_squares(n): Some positive integers can be expressed as a sum of two squares of some positive integers greater than zero. For example, 74 = 49 + 25 = 7^2 + 5^2. This function should find and return a tuple of two positive integers whose squares together add up to n, or return None if the parameter n cannot be broken into a sum of two squares.To facilitate the automated testing, the returned tuple must present the larger of its two numbers first. Furthermore, if some integer can be broken down to a sum of squares in several ways, return the breakdown that maximizes the larger number. For example, the number 85 allows two such representations 7^2 + 6^2 and 9^2 + 2^2 , of which this function must return (9, 2).The technique of two approaching indices that start from the beginning and end of a sequence, respectively, and approach each other until they meet somewhere is directly applicable to this problem. In this problem, these indices crawl towards each…
Must be written in the coral language. Complete the PrintArray function to iterate over each element in dataValues. Each iteration should put the element to output. Then, put "*" to output. Ex: If dataValue's elements are 2 4 7, then output is: 2*4*7*
