1c) Average sentence length 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: 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). 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.) Calculate the average sentence length, returning this from your function: 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. 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 3.0.

1c) Average sentence length

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:

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).
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.)
Calculate the average sentence length, returning this from your function:
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.
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 3.0.
