I am a newbie in Python. I hope the guru can advise me on the following
I am trying to open a web page from command line. If the web page is not
valid, I hope to capture the exception and print an error message and
What I currently have is as below, but I am certain I used the wrong
class because I did not managed to capture the exception (if any) raise.
Could someone teach me how to test the validity of a web page, ie
whether does it exist, can it be open?
# If web page is entered, check whether it is a valid web page
inf = urllib.URLopener.http_error_default(sys.argv)
print "Invalid webpage!"
print "Usage : ./webmap.py http://server-name/path-to-document"
