Python Dictionary

#=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
#Takes a list of words from a specified file, runs them
# through dictionary.com and prints the definitions in a
# new text document.  Very useful for when your teacher
# wants to give you homework, but there's nothing left
# to assign, so she makes you copy 127 definitions from
# the back of the book due the next day making you realize
# what a waste of time the class is so you just make this
# program instead...  Anyway, here it is.
#
#Note: Only takes the first definition from each search.  You can easily
#      change this by making it look for 2.</td><td> rather than 1.
