Iterate through the list so that if the character ‘m’ is in the string, then it should be added to a new list called m_list. Hint: Because this isn’t just a list of lists, think about what type of object you want your data to be stored in. Conditionals may help you.

d = ['good morning', 'hello', 'chair', 'python', ['music', 'flowers', 'facebook', 'instagram', 'snapchat', ['On my Own', 'monster', 'Words dont come so easily', 'lead me right']], 'Stressed Out', 'Pauver Coeur', 'Reach for Tomorrow', 'mariners song', 'Wonder sleeps here'] ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(m_list, ['good morning', 'music', 'instagram', 'On my Own', 'monster', 'Words dont come so easily', 'lead me right', 'Reach for Tomorrow', 'mariners song'], "Testing that m_list has the correct list assigned to it.") myTests().main()

The nested dictionary, pokemon, shows the number of various Pokemon that each person has caught while playing Pokemon Go. Find the total number of rattatas, dittos, and pidgeys caught and assign to the variables r, d, and p respectively. Do not hardcode. Note: Be aware that not every trainer has caught a ditto.

pokemon = {'Trainer1': {'normal': {'rattatas':15, 'eevees': 2, 'ditto':1}, 'water': {'magikarps':3}, 'flying': {'zubats':8, 'pidgey': 12}}, 'Trainer2': {'normal': {'rattatas':25, 'eevees': 1}, 'water': {'magikarps':7}, 'flying': {'zubats':3, 'pidgey': 15}}, 'Trainer3': {'normal': {'rattatas':10, 'eevees': 3, 'ditto':2}, 'water': {'magikarps':2}, 'flying': {'zubats':3, 'pidgey': 20}}, 'Trainer4': {'normal': {'rattatas':17, 'eevees': 1}, 'water': {'magikarps':9}, 'flying': {'zubats':12, 'pidgey': 14}}} ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testSix(self): self.assertEqual(r, 67, "Testing that r is assigned to correct value.") def testSixB(self): self.assertEqual(d, 3, "Testing that d is assigned to correct value.") def testSixC(self): self.assertEqual(p, 61, "Testing that p is assigned to correct value.") myTests().main()

Below, we have provided a nested list called big_list. Use nested iteration to create a dictionary, word_counts, that contains all the words in big_list as keys, and the number of times they occur as values.

big_list = [[['one', 'two'], ['seven', 'eight']], [['nine', 'four'], ['three', 'one']], [['two', 'eight'], ['seven', 'four']], [['five', 'one'], ['four', 'two']], [['six', 'eight'], ['two', 'seven']], [['three', 'five'], ['one', 'six']], [['nine', 'eight'], ['five', 'four']], [['six', 'three'], ['four', 'seven']]] ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(sorted(word_counts.items()), sorted([('eight', 4), ('five', 3), ('four', 5), ('nine', 2), ('one', 4), ('seven', 4), ('six', 3), ('three', 3), ('two', 4)]), "Testing that word_counts was created correctly.") myTests().main()

Provided is a dictionary that contains pokemon go player data, where each player reveals the amount of candy each of their pokemon have. If you pooled all the data together, which pokemon has the highest number of candy? Assign that pokemon to the variable most_common_pokemon.

pokemon_go_data = {'bentspoon': {'Rattata': 203, 'Pidgey': 120, 'Drowzee': 89, 'Squirtle': 35, 'Pikachu': 3, 'Eevee': 34, 'Magikarp': 300, 'Paras': 38}, 'Laurne': {'Pidgey': 169, 'Rattata': 245, 'Squirtle': 9, 'Caterpie': 38, 'Weedle': 97, 'Pikachu': 6, 'Nidoran': 44, 'Clefairy': 15, 'Zubat': 79, 'Dratini': 4}, 'picklejarlid': {'Rattata': 32, 'Drowzee': 15, 'Nidoran': 4, 'Bulbasaur': 3, 'Pidgey': 56, 'Weedle': 21, 'Oddish': 18, 'Magmar': 6, 'Spearow': 14}, 'professoroak': {'Charmander': 11, 'Ponyta': 9, 'Rattata': 107, 'Belsprout': 29, 'Seel': 19, 'Pidgey': 93, 'Shellder': 43, 'Drowzee': 245, 'Tauros': 18, 'Lapras': 18}} ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(most_common_pokemon, 'Rattata', "Testing that most_common_pokemon has the correct value.") myTests().main()
