Quiz - 4

Develop the function valores_extremos which takes the parameter numeros, 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 numeros list. Solve the problem without using the functions max nor min.

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

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

Develop the function pares_e_impares which takes the parameter numeros. numeros 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 numeros, respectively.

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

Develop the function intercalar_listas 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:
intercalar_listas([1, 3, 5, .....], [2, 4, 6, ....]) -> [1, 2, 3, 4, 5, 6, ....]

def intercalar_listas(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( intercalar_listas(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( intercalar_listas(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 buscar_palabras will be passed the following texto 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 buscar_palabras(texto): ==== 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(buscar_palabras(text), res, f"Expected: {res}") myTests().main()

Now you will develop the function buscar_palabras_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 texto that have any of the letters in the string "python", and also have a length greater than 4 characters.

def buscar_palabras_2(texto): ==== 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(buscar_palabras_2(text), 24, "Expected: 24") myTests().main()
