We will create a function ( avg_sentence_len ) to calculate the average sentence length across a piece of text. This function should take text as an input parameter. Within this function: 1. sentences : Use the split() string method to split the input text at every '.'. This will split the text into a list of sentences. Store this in the variable sentences. To keep things simple, we will consider every "." as a sentence separator. (This decision could lead to misleading answers. For example, "Hello Dr. Jacob." is actually a single sentence, but our function will consider this 2 separate sentences). 2. words : Use the split() method to split the input text into a list of separate words, storing this in words . Again, to limit complexity, we will assume that all words are separated by a single space (" "). (So, while "I am going.to see you later" actually has 7 words, since there is no space after the ".", so we will assume the this to contain 6 separate words in our function.) 3. Calculate the average sentence length, return ing this from your function: 4. if the last value in sentences is an empty string: the average sentence length should be the number of words divided by the len(sentences) - 1. 5. otherwise, the average sentence length should be the number of words divided by the number of sentences . For the "I am going.to see you later" example, your function should return 1.5.
