{code}

Python code:
{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)
{code}

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
