Greetings from NumPy!
Nearly all branches of research and engineering use the free source Python library known as NumPy (Numerical Python). It is the de facto standard for manipulating numerical data in Python and forms the basis of both the PyData and scientific Python ecosystems. Users of NumPy range from novice programmers to seasoned academics working on cutting-edge academic and commercial research and development. The majority of other Python data science and scientific programs, including Pandas, SciPy, Matplotlib, sci-kit-learn, and sci-kit-image, make substantial use of the NumPy API.
Data structures for multidimensional arrays and matrices are available in the NumPy library (more on this is covered in the next sections). It offers ways to effectively manipulate the homogeneous n-dimensional array object ndarray. With NumPy, a variety of mathematical operations may be performed on arrays. It provides a vast library of high-level mathematical functions that work on these arrays and matrices, as well as strong data structures that ensure efficient calculations with arrays and matrices.

- Write a statement that will copy the string “Beethoven” to the array composer.arrow_forwardThis program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team. (1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99) and the player's rating (1 - 9). Store the jersey numbers in one int array and the ratings in another int array. Output these arrays (i.e., output the roster). Ex: Enter player 1's jersey number: 84 Enter player 1's rating: 7 Enter player 2's jersey number: 23 Enter player 2's rating: 4 Enter player 3's jersey number: 4 Enter player 3's rating: 5 Enter player 4's jersey number: 30 Enter player 4's rating: 2 Enter player 5's jersey number: 66 Enter player 5's rating: 9 ROSTER Player 1 -- Jersey number: 84, Rating: 7 Player 2 -- Jersey number: 23, Rating: 4 (2) Implement a menu of options for a user to modify the roster.

- I want this work be done in C# Visual studio. Given the following: private void btnRun_Click(object sender, EventArgs e){//Your code goes here } Code the statement(s) that will create a integer array of 5 elements and initialize the array with the following values in one line of code 10, 15, 20, 25, and 30. Then using a for loop alter the values in each element of the array by adding 5 to it. So after the for loop runs the values of the array should be 15, 20, 25, 30, and 35.arrow_forwardPlease write your own original code. Objective Create a program that initializes and works with string variables. Create a program named LastnameFirstname15.c, that does the following: Note: There is no user input for this program. Declare and initialize a char array that stores your first name in title case. Title case means the first letter is uppercase and the rest is lowercase. Ensure the size/length of the array is equal to the length of your name plus the null character.As an example, my first name is Edward, therefore the size of the array will be 7.char firstname[7] = "Edward"; Declare and initialize another char array that stores your last name in title case. Ensure the size/length of the array is equal to the length of your name plus the null character. Use the strlen function to get the lengths of each name and store them in separate variables. Calculate the total length of your name by adding the lengths of the first name and last name and store it in another…arrow_forwardC++ you have to you use #include <random> also included a sample output has too match the layout Thank youarrow_forward
- Take arr as any integer array of any size.arrow_forwardHello, Stuck on this question. All programming is in Python. 2.) Design a program that generates a 7-digit lottery number. The program should have an INTEGER array with 7 elements. Write a loop that steps through the array, randomly generating a number in the range of 0 through 9 for each element. Then write another loop that displays the contents of the array. All programming is in Python.arrow_forward//write code that loops through the two variables returns an array ['2 is zwei', '3 is drei', '4 is vier', '5 is fünf', '6 is sechs']// example:// return: ['2 is zwei', '3 is drei', '4 is vier', '5 is fünf', '6 is sechs']// hint: use Array.forEach, Array.map or a for loopfunction germanNumbers(){ const cardinalNumbers = [2,3,4,5,6]; const germanNumbers = ['zwei', 'drei', 'vier', 'fünf', 'sechs']; } // write code that returns an array of ONLY prime numbers that are in the array numbers// example: // return [2, 3, 5, 7, 11, 13]// hint use: Array.filterfunction returnPrimeNumbers(){ const numbers = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]; }arrow_forward
