This error is common for older script with python version up to 3.7 (https://docs.python.org/3.7/library/functions.html#open)

And a previous error (corrected by a simple and ugly command 'sudo cp -s /usr/bin/python3 /usr/bin/python' ), 'python' for most modern system do not exist anymore and must be remplace by 'python3'
