 HW2 How to get started with Problem 3 Questions Go over code from quiz question 4 Scrabble bingo data: words in the dictionary and letters on tiles go through each word in the dictionary, check if it can be made with the tiles annoying to have a separate variable for each letter, impossible to have one for each word need to way to group a bunch of related data together! Python gives us the list think of it as a slot in memory with its own numbered slots inside NUMBERING STARTS AT ZERO! tiles = ["D", "O", "B", "Y", "E", "G", "O"] print(tiles) D print(tiles) O print(tiles) IndexError print(tiles[-2]) G lists can be modified tiles = "L"print(tiles) # prints ["D", "O", "L", "Y", "E", "G", "O"] We still need a way to avoid a separate line of code for each possible word Examine our sequence of copy-pasted code—what changes each time? We need a structure that repeats the same thing over-and-over, except changing one thing each time: for loop for in : for word in words: # check if tiles can make word quick check: given a variable nums that stores a list, write a for loop that prints out each element of the list for num in nums: print(num) import syswords = ["bogeyed", "goodbyes", "goodbye", "phantasmagorical"]tiles = ["D", "O", "B", "Y", "E", "G", "O"]for word in words: check = tiles.copy() for letter in word: if letter in check: check.remove(letter) if len(check) == 0 and len(word) == len(tiles): print("The Scrabble tiles", tiles, "can be played as a bingo:", word) sys.exit()print("The Scrabble tiles", tiles, "cannot be played as a bingo") strings are sequences just like lists, so we can loop over each letter with for letter in word use the in keyword to get True or False for a value being present in a sequence len is a function that takes a sequence and returns the number of elements in that sequence
