Quiz - 4

Develop the function extreme_values which takes the parameter numbers, representing a list of 10 random numbers between 0-100. The function should return a tuple (a, b), where a and b are the maximum and minimum values respectively of the numbers list. Solve the problem without using the functions max nor min.

Example:
extreme_values([15, 48, 0, 27, 13, 62, 32, 57, 85, 18]) -> (85, 0)

def extreme_values(numbers): ==== from unittest.gui import TestCaseGui from random import sample class myTests(TestCaseGui): def testOne(self): numbers = sample(range(100), 10) self.assertEqual( extreme_values(numbers), (max(numbers), min(numbers)), f"Expected: ({max(numbers)}, {min(numbers)})" ) def testTwo(self): numbers = sample(range(100), 10) self.assertEqual( extreme_values(numbers), (max(numbers), min(numbers)), f"Expected: ({max(numbers)}, {min(numbers)})" ) def testThree(self): numbers = sample(range(100), 10) self.assertEqual( extreme_values(numbers), (max(numbers), min(numbers)), f"Expected: ({max(numbers)}, {min(numbers)})" ) myTests().main()

Develop the function even_and_odd which takes the parameter numbers. numbers represents a list of 20 random numbers between 1-100. The function should return a tuple of lists of the form ([even], [odd]), where even and odd are lists of even and odd numbers that are in numbers, respectively.

def even_and_odd(numbers): ==== from unittest.gui import TestCaseGui from random import sample class myTests(TestCaseGui): def testOne(self): numbers = sample(range(1, 100), 20) self.assertEqual( even_and_odd(numbers), ([n for n in numbers if n % 2 == 0], [n for n in numbers if n % 2 != 0]), f"Expected: ({[n for n in numbers if n%2 == 0]}, {[n for n in numbers if n%2 != 0]})", ) def testTwo(self): numbers = sample(range(1, 100), 20) self.assertEqual( even_and_odd(numbers), ([n for n in numbers if n % 2 == 0], [n for n in numbers if n % 2 != 0]), f"Expected: ({[n for n in numbers if n%2 == 0]}, {[n for n in numbers if n%2 != 0]})", ) def testThree(self): numbers = sample(range(1, 100), 20) self.assertEqual( even_and_odd(numbers), ([n for n in numbers if n % 2 == 0], [n for n in numbers if n % 2 != 0]), f"Expected: ({[n for n in numbers if n%2 == 0]}, {[n for n in numbers if n%2 != 0]})", ) myTests().main()

Develop the function collate_lists which takes two parameters, l1 and l2, representing lists of 10 random numbers between 1-100. The function should generate a third list composed of the elements of l1 and l2 interleaved. This third list will be returned.

Example:
collate_lists([1, 3, 5, .....], [2, 4, 6, ....]) -> [1, 2, 3, 4, 5, 6, ....]

def collate_lists(l1, l2): ==== from unittest.gui import TestCaseGui from random import sample class myTests(TestCaseGui): def testOne(self): l1 = sample(range(100), 10) l2 = sample(range(100), 10) self.assertEqual( collate_lists(l1, l2), [val for pair in zip(l1, l2) for val in pair], f"Expected: {[val for pair in zip(l1, l2) for val in pair]}", ) def testTwo(self): l1 = sample(range(100), 10) l2 = sample(range(100), 10) self.assertEqual( collate_lists(l1, l2), [val for pair in zip(l1, l2) for val in pair], f"Expected: {[val for pair in zip(l1, l2) for val in pair]}", ) myTests().main()

The function search_for_words will be passed the following text as argument:
“The Python Software Foundation and the global Python community welcome and encourage participation by everyone. Our community is based on mutual respect, tolerance, and encouragement, and we are working to help each other live up to these principles. We want our community to be more diverse: whoever you are, and whatever your background, we welcome you.”
It should generate a list of words from this text using split(). Then it should create a list of words that start or end with any of the letters in the string "python". This list is the one that will be returned. Note: Don’t forget to first remove special characters and be careful with capitalization.

def search_for_words(text): ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): text = """The Python Software Foundation and the global Python community welcome and encourage participation by everyone. Our community is based on mutual respect, tolerance, and encouragement, and we are working to help each other live up to these principles. We want our community to be more diverse: whoever you are, and whatever your background, we welcome you.""" res = [ word for word in text.lower().replace(".", "").replace(",", "").split() if word[0] in "python" or word[-1] in "python" ] self.assertEqual(search_for_words(text), res, f"Expected: {res}") myTests().main()

Now you will develop the function search_for_words_2, which will be passed the previous text as a parameter. Again you will separate the text into words, just like you did in Exercise 4. This time, you should calculate the number of words within text that have any of the letters in the string "python", and also have a length greater than 4 characters.

def search_for_words_2(text): ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): text = """The Python Software Foundation and the global Python community welcome and encourage participation by everyone. Our community is based on mutual respect, tolerance, and encouragement, and we are working to help each other live up to these principles. We want our community to be more diverse: whoever you are, and whatever your background, we welcome you.""" self.assertEqual(search_for_words_2(text), 24, "Expected: 24") myTests().main()
