In this case, you can tell by the except clause.  except: can only follow a 
try:, and they must be on the same indent level.  Also, if the try: was in 
'def foo()', 'bar()' would have to have a higher indent level than 'line = 
sys.stdin.readline()'.  (From what I can see, it does, but I'm not sure that 
was intended, as the except came in at a different indent level from either)  
So for this example, the try: belongs in 'def main()'
