Challenge #5: Monkey Business
Document Actions
This exercise depends on a simple but unusual technique.
The 'string' library in Python has a function 'capwords': http://python.org/doc/lib/node110.html
You already have a program that uses this function to display headlines, but your editorial guidelines have changed. Now, a word should not be capitalized if it is three letters or less. Write a new function that does this. But the problem is that you call 'capwords' all over the place already. Can you make a change in one place so that you don't have to change all these occurrences? Demonstrate how.
For a hint, use a decoder from challenge 3 to read this string:
wklv whfkqltxh lv xvxdoob fdoohg prqnhb sdwfklqj

Not that these plain text files are much better, really....
