Task 4 Suppose you have a sitting arrangement of the students who will give the final exam in a list. The list contains the last two digits of their student ID as given below. sitting_list = [10,30,20,70,11,15,22,16,58,100,12,56,70,80] Now you want to organize the sitting arrangement of the students in your own way. You decide to sort all the students in the even indices of the list in ascending order and all the students in the odd indices of the list in descending order. So, write a python program that organizes the list for you in this way. Sample Output (10, 100, 11, 80, 12, 70, 20, 56, 22, 30, 58, 16, 70, 15]

The QObject class is a simplified application of the composite pattern because it plays the role of all the classes in the pattern. True or false

In python don't import libraries

What is the maximum number of exchanges involving any particular element during selection sort? What is the average number of exchanges involving an element?

What's wrong with this cell?

I need the references for the answers

Your favorite soccer player is playing in the world cup and the match has ended in a tie. As the teams get ready for the penalty shootout, you know your favorite player will be last to shoot. A quick search tells you that your favorite player makes a goal when kicking from the penalty mark 0.76% of the time. You also know that the player before your favorite player makes a kick from the penalty mark 0.70% of the time. You also know that neither player is impacted by kicks before they take the shot. What is the probability that both players miss their kicks? Report your answer to the second decimal point, that is, 0.45 instead of 0.5.

Hello thank you for the solution. Is there also a way to format the list without using the .join method, and just using f' strings, perhaps in a list comprehension?

TODO 12 Let's now split our input data X and labels y into a train and test set using the train_test_split() function (docs). Here we'll use the 80-20 split rule where we use 80% of the data for training and 20% for testing. Lastly, we'll seed our split using the random_state keyword argument which will make sure we create the same split every time we run the function. Use the train_test_split() function to get a train and test split. Store the output into X_train, X_test, y_train, and y_test. Pass the required arguments X and y. Further specify we want to use 20% of the training data by setting the test_size keyword argument. Lastly, pass the keyword argument random_state=42 to set the random seed so we get the same split every time we run this code. Print the shape for X_train. Print the shape for y_train. Print the shape for X_test. Print the shape for y_test. # TODO 12.1X_train, X_test, y_train, y_test =  todo_check([    (X_train.shape == (413, 29), 'X_train does not have the…
