import pdblp
con = pdblp.BCon(debug=True, port=8194)
con.start()

Why?

This library is a wrapper on top of the python bloomberg API, blpapi which handles the communication with the Bloomberg Service. This error is telling you that you cannot connect to the Bloomberg Service. You will need to make sure you are running a Bloomberg Professional Terminal on the machine you are attempting to connect from. This should also work with B-PIPE although I have not tested this.

I would take a look at pandas-datareder https://github.com/pydata/pandas-datareader which has some functionality around interfacing with free data sources.
