Problem 2: Write a Python function, called cntWordsOccur, that takes in one argument. Argument #1: It is a list of strings. The function will count the number of times the same string occurs in the list and builds a list of lists. Each list with have the string in the 0th index position and the count in the 1st index position. You will return the list of lists created. You can use any of the built in functions. def cntWordsOccur (sentences): YOUR CODE GOES HERE >>list_words["I", "I","am", "a, "cat", "dog", "a", >print (cntWordoccur (list_words)) I"I", 2], ["am", 1, "a", 2, [ "cat", 1], ["dog", 11]
