input1.txt hello hello hello world Read all words into a list To open and close the file within every function to get the list of words, let's write a helper function getallWords (). The split() function will be useful to achieve this. def getallwords (filepath): Returns a list of all words from the given filepath. The function opens the file for reading, and closes the file before returning. return "stub" For example, getAllWords ("input1.txt") returns ["hello", "hello", "hello", "world"]; getAllWords ("input2.txt") returns ["hello", "world", "world", "world"]
