Unfortunately, much of our data was collected long before then - and as we've discovered, the OP is still living in Python 2 times. What about if the path "name" (above) is not in utf-8? eg the OP's Montréal in Latin1, as Montréal.txt or Montréal.rpt -- Regards, =dn

When the list of dictionaries is processed, I would have to check each element to see if it is empty. That strikes me as being less efficient than filtering out the empty dictionaries in one go, although obviously one would need to benchmark that.

Problem using cx_Freeze

Aug. 16, 2022

I’m trying to use cx_Freeze (https://pypi.org/project/cx-Freeze/) in a python app but running into an error message: AttributeError: module 'cx_Freeze' has no attribute ‘BdistDMG’ I’m using Anaconda and error appears with the import command: from cx_Freeze import * From the terminal the command: python setup.py build gives much the same error. I believe there is an issue specifying the output file name but don’t know how to resolve it. Any suggestions, thanks. David
