Code the following in Python.

1.Assume each of the variables set1 and set2 references a set. Write code that creates another set containing the elements that are not shared by set1 and set2, and assigns the resulting set to the variable set3.

 

2.Assume the following list exists:

numbers = [1, 2, 3, 4, 5]

Write a statement that uses a dictionary comprehension to create a dictionary in which each element contains a number from the numbers list as its key, and the product of that number times 10 as its value. In other words, the dictionary should contain the following elements:

{1: 10, 2: 20, 3: 30, 4: 40, 5: 50}

 

3.Assume the following dictionary exists:

test_averages = {'Janelle':98, 'Sam': 87, 'Jennifer':92, 'Thomas':74, 'Sally':89, 'Zeb':84}

Write a statement that uses a dictionary comprehension to create a second dictionary named high_scores. The high_scores dictionary should contain all the elements of the test_averages dictionary in which the value is 90 or greater.
