Traceback (most recent call last):
ValueError: unknown url type: w1.weather.gov/obhistory/KDCA.html
copy the url from the error message into my browser and get the page.
Browsers have evolved to make all sorts of intelligent guesses about
what the true URL is based on what the user types in. They try
pre-pending various types and pre and post fixes (for example
you can usually miss out the www part or the .com part).
Urlopen makes no such assumptions, you must provide the full url
(with the exception of the port) including the type (ftp, mail,
http etc)
