#933

Now the interpreter gives a syntax error. I think the previous version was correct.

 File "/home/nikita/Dev/try_python/20_test_zmq/06_wuclient.py", line 19
    zip_filter = sys.argv[1] if len(sys.argv) > 1 and sys.argv[1] == "10001"
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: expected 'else' after 'if' expression
