Use the arrays below, X and w Calculate the dot product of X and w. Put the outcome inside the variable dotted_array. X = np.ones((5, 5)) w = np.arange(5).reshape(1, -1) print(f"X shape: {X.shape}") print(f"w shape: {w.shape}") # TODO 1 dotted_array = print(f"dotted_array output: \n {dotted_array}") print(f"dotted_array shape: {dotted_array.shape}") todo_check([ (dotted_array.shape == (5,1),'dotted_array does not have the correct shape of (5,1)'), (np.all(dotted_array == np.array([10,10,10,10,10])),'dotted_array does not have the correct values') ])

Create an array called sales to monitor one week's worth of sales over the course of two months. Assign sales data to the array's elements. Then, in a loop, compute the average sales for the one week of each of the two months that are recorded in the array.

TicTacToeCreate the board display the board Set token to ‘x’Loop //at most 9 times, but end loop when someone wins{ Ask player where to place token display the board Checks if won Change token (if it was ‘x’ change to ‘o’ and vice versa)}Either congratulate someone on winning or say it was a draw. Create a 17x17 array of characters and put ‘ ‘ in each element.2. Write a loop to make the first horizontal line, and another to do the second horizontal line3. Write a loop to make the first vertical line, and another to create the second vertical line4. Put in the numbers (this is so the player can choose where to put the token). You will need 9 separate assignment statements.

How do you keep track of which entries in a partially filled array contain data?

5 نقاط Q1. Write a code to find the summation of all numbers that are less than or equal to 10 in the array. C= {-10, 35, 10, -5, 6, 16, -23, 94, -22, 12, 202, -52O, 0, .-3}

In [ ]: We obtained an array with N = 10 values, scattered about mean of 25 (mm). Let's calculate the mean, standard deviation, standard deviation of the mean and 20-uncertainty SL of these numbers. In the following code, do these steps: • In the first cell, add a brief comment that explains what each statement does. Start each comment with a # sign. • In the second cell, delete the raise Not ImplementedError() code line and print the standard deviation and 20-uncertainty on the screen (follow the example for mean_L) mean_L = np.mean (L) print("Mean length: ", mean_L) stddev_L = np. std (L, ddof=1) stddev_mean_L = stddev_L/np.sqrt(N) uncertainty_L = 2*stddev_mean_L In [ ] V #YOUR CODE HERE raise NotImplementedError() #calculates the mean of L In the above code, the green expressions on the right hand side, such as np.mean, np. std and np.sqrt are functions built into the numpy package of Python. The names on the left hand side are variable names invented by me.
