      Python code:

      from pyignite import Client
      
      client = Client()
      client.connect('127.0.0.1', 10800)
      cache = client.get_or_create_cache("test_3")
      cache.put("key3", -3.3)
      

      All others thin clients from same sources and on the same ignite binary works well
      On linux from same sources python client works well too
      Troubles only with python and windows
