"SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?" error message for SOPHIE spectra

[andreok]

Hello,

I'm trying to process some archived SOPHIE spectra (only public data from the data archive) and I'm getting the following error message:

Traceback (most recent call last):

SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

It seems that indeed there're missing parentheses in the call to print(), but I would like to understand the reason why it's complaining about the data being proprietary. Should I just ignore this warning?

Thanks, Andre
