Python If With no commands followed by a Else Syntax error

I'm writing a basic webscraping code, which basically will get the date and title of a post and, if the date >= a date stored in a SQL db and the title != from a title also stored in the DB, then do some stuff.

I'm getting a syntax error when executing it. Here's the code:

for i in web_results:
    py_newsdate = datetime.strptime(i.find('div', attrs={'class': "infoItem"}).find_all('p')[0].getText()[6:], '%d/%m/%Y')
    py_newstitle = i.find('h3').find('a')['title'] 

    if (py_newsdate < sql_latest[0][0] or py_newstitle == sql_latest[0][1]):
    else:
        py_newslink = i.find('h3').find('a')['href'] 
        web_results_final.append([py_newsdate, py_newstitle, py_newslink])

print(web_results_final)

And here's the error:

  File "searcher", line 37
    else:
       ^
IndentationError: expected an indented block

I know the blocks have to be properly idented, but I'm thinking the problem may be on this "empty" if.

Thanks.

It will be more efficient if you use, 

if not (py_newsdate < sql_latest[0][0] or py_newstitle == sql_latest[0][1]):
    py_newslink = i.find('h3').find('a')['href'] 
    web_results_final.append([py_newsdate, py_newstitle, py_newslink])

Blocks need to be followed by something. If you have a block you intend to leave empty, then use the pass statement:

if (py_newsdate < sql_latest[0][0] or py_newstitle == sql_latest[0][1]):
    pass
else:
    py_newslink = i.find('h3').find('a')['href'] 
    web_results_final.append([py_newsdate, py_newstitle, py_newslink])

This is true whether you are trying to write the block inline or on multiple lines:

if 0: pass
else: print(2)

Note: you have to have a new line for an else block. This will not work:

if 0: pass; else: print(2)
