Required tests - a password *must* pass these tests in order to be considered strong: [1] Enforce a minimum length [2] Enforce a maximum length [3] Forbid repeats: may not contain sequences of three or more repeated characters An array of optional tests. These tests are "optional" in two senses:1. Passphrases (passwords whose length exceeds min phrase length) are not obligatedto pass these tests provided that allow pass phrases is set to Boolean true (which it isby default).2. A password need only to pass # min optional tests in order to pass these optional tests andbe considered strong.Optional tests: [4] Contains at least one lowercase letter [5] Contains at least one uppercase letter [6] Contains at least one digit [7] Contains at least one special character (not alpha, not digit) Output:Your program will produce the following output for each password that it processes: Failed Tests : [1-3] or [1-7] Passed Tests : [1-3] or [1-7] Required Test Errors: [ 'The password must be…

Implementing Set Operations The code template initializes two sets, A and B containing lower case characters as elements.Block 1 computes A-B and prints out the resulting set.In Block 2 write code to compute B-A and output the resulting set.In Block 3 write code to compute A⊕B and output the resulting set. Note that according to the definition of a set, the order of the elements does not matter. In this code, the elements of a set are printed in sorted order so that your output will match the expected output in the test cases. main.py # Initialize sets A and BA = { 'a', 'b', 'c', 'd', 'e', 'f' }B = { 'c', 'd', 'f', 'h', 'j', 'k' } print('A = ', sorted(A))print('B = ',sorted(B))print(' ')#Block 1: computes and prints out the set A - B AminusB = set()for element in A: # this line runs through every element in Aif not(element in B): #A - B is the set of elements that are in A and are not in BAminusB.add(element) # Add it AminusB every element in A if the element is also not in B print('A…
