Are you sure, that there is no invisible character at the end
of that line?

When I try code like the above (in PYthon 2.7), there is no
"SyntaxError":

>>> while(False):
...     try :
...         # read line from file:
...         print(file.readline())
...         # parse
...         parse_json(file.readline())
...         count = count - 1
...     except socket.error as e:
...         print('Connection fail', e)
...         print(traceback.format_exc())
... 
>>> 


Another reason for your problem could be an older Python version.
The "as" construct as part of the "except" clause is a more recent
addition to Python.
