Hellow :)

I have a program – written in Python 2.7.3 and wxPython 2.9.4.0 – that uses Python's urllib2.urlopen() function/method. The purpose of my program is to count the occurence of a user-given word that exists on a user-given website. So if I want to know how many times the word "library" occurs on "wxpython.org", I type in the URL box "http://www.wxpython.org" (without quotes), and in the word box I type "library" (without quotes).

My problem is that the user needs to be exact at inputting the URL, because "wxpython.org" is not enough; it has to be inputted exactly as "http://www.wxpython.org", which is rather annoying for the user.

Is there a way the URL be inputted only as "wxpython.org" and urllib2.urlopen's function/method filling in the missing "http://www." part? Or is there any other way like checking for the "http://www." part and prepend it if not present? What is the best way to solve my issue and how exactly should I go and implement the solution?

There is, and that's probably why it is your homework
assignment. You need to read up on string handling.

So I can't do anything else than use the ol' string handling technique of prepending the missing "http://www." if it's missing in the URL?

The "http://" part is really required.� The latest round of browsers is making people lazy, because they fill that in if it's not provided.� I still find myself typing it by hand.� It's not hard to detect this, however.� Remember that there are a lot of protocols available for URLs.� There's no reason for urllib to assume that you meant "http".� If your program knows that http:// is the default, then it's up to you to provide it.

The "www" part is different.� That's not universal.� You should be able to fetch http://wxpython.org and have it work just fine.� You might get a "redirect" response telling you to fetch www.wxpython.org instead, but that's something you need to be handling.

Is there any HTTP URL-validating function/method in Python/wxPython?
