This program deals with text files, writing and reading files, and using Python to process files.

Problem #1

Write a program that reformats text files and rewraps the text to a specified width.

Here is an example. Assume you have a text file called CNN.txt that contains this text (taken from Google news on 4/2/14):

Washington (CNN) -- If you're rich and want to give money to a lot of political campaigns, the Supreme Court ruled Wednesday that you can. The 5-4 ruling eliminated limits on how much money people can donate in total in one election season. However, the decision left intact the current $5,200 limit on how much an individual can give to any single candidate during a two-year election cycle. Until now, an individual donor could give up to $123,200 per cycle.

Let's assume that the program is set to rewrap the text in the file to a width of 30 characters, here is what it would write back in the file, after having read it:

Washington (CNN) -- If you're
rich and want to give money to
a lot of political campaigns,
the Supreme Court ruled
Wednesday that you can. The
5-4 ruling eliminated limits
on how much money people can
donate in total in one
election season. However, the
decision left intact the
current $5,200 limit on how
much an individual can give to
any single candidate during a
two-year election cycle. Until
now, an individual donor could
give up to $123,200 per cycle.

If the program had been set to wrap at 10, this is what it would have stored in the file:

Washington
(CNN) --
If you're
rich and
want to
give money
to a lot
of
political
campaigns,
the
Supreme
Court
ruled
Wednesday
that you
can. The
5-4 ruling
eliminated
limits on
how much
money
people can
donate in
total in
one
election
season.
However,
the
decision
left
intact the
current
$5,200
limit on
how much
an
individual
can give
to any
single
candidate
during a
two-year
election
cycle.
Until now,
an
individual
donor
could give
up to
$123,200
per cycle.
