if you read the bittrex documentation here: https://bittrex.com/Home/Api carefully there is a python api wrapper already created: https://github.com/ericsomdahl/python-bittrex

I am not familiar with python to help you there but here are my suggestions to fix your own code:
- check your "urlrequest" to see if it is correct address or not. for example to getOpenOrders it should be like this
https://bittrex.com/api/v1.1/market/getopenorders?apikey=BlahBlahApiKeyString&nonce=1475048767
nonce is not time it is epoch time (google it) the time of this comment is: 1475048767
