Write a program that takes a string as input, strips whitespace and punctuation from the words, and converts them to lowercase.

Hint: The string module provides strings named whitespace, which contains space, tab, newline, etc., and punctuation which contains the punctuation characters. Let’s see if we can make Python swear:

 

 

Part 2.  Modify the program from part 1 above  to count the total number of words in the string, and the number of times each word is used.  Use a dictionary to store the frequency of each word.  Your data structure should look something like:

>>> import string >>> print string.punctuation ! " # $ % & '()*+,-./:; ?@[\]^_^ {|}~\
