Says that you are trying to change the character 'i' into
an integer, which won't work.  Put a print statement just
before your for loop and print out url.  It doesn't just
contain numbers (as apparently you think it does).

You should also lose the semicolons, you are writing Python
now, not PHP ;-).

You might also want to write:

def strord(url):
    return [int(i) for i in url]

Or just lose the function completely since it degrades to a
single list comprehension.
