Error with websocket connection to the Elektron feed

g.suhharukov

I run the following code https://github.com/Refinitiv/websocket-api/blob/master/Applications/Examples/python/market_price_authentication.py , in two different IDE (Pycharm and Jupyter). In Pycharm it is perfectly working, however Jupyter it gives an error

During handling of the above exception, another exception occurred:

    353     for opt, arg in opts:

Could you tell how to solve this problem?

Hello @g.suhharukov

I can replicate the issue with the market_price.py in Jupyter Notebook environment (as .ipynb file). The notebook application encounters the issue in the same place. It seems there is a problem between Python's getopt module when running it in IPython/Notebook environment.

If I comment on an entire "# Get command line parameters" section and set all required parameters, the notebook application work fine.
