Question

Ok.This is my first question here
So I’m trying to make this program which searches for the phrase “You have an error” in the HTML source code.The problem is when I try

    html_data=urllib2.open(site).read()
    if html_data.find(string):
       print "It's found"

It doesn’t find it..Although when I print html_data it is found in there with no tags whatsoever.
Can anybody help me on this?

Answer 1

str.find() returns the index (or -1 if not found). Thus the following is incorrect:

if html_data.find(string):

It should be:

if html_data.find(string) != -1:

Alternatively, if you don’t need to know the position of the match:

if string in html_data:
