I guess my only thought is that this "static analyzer" is simply a holdover from your Java/C++ programming experience. It just doesn't really make sense in a dynamic language. I'd rather spend my time actually writing the documentation than litter my code so some other software can do it for me. I'm not saying it isn't a good idea in Java, I'm just not sold on the concept in python. Just write doc strings, people have already written utilities to parse and display them. > In the context of the original question > "where and how should we assign class members in order > to flag member names and types to static analyzers like > Doxygen or pylint?" > I understood that people were agreeing > "Yes, assigning each member token values in the __init__() > method is a good practice". > > >>> I think I'm hearing a general yes on that - any other opinions? >>> >> Not sure where you think you are hearing a yes, I am hearing a lot of >> objections. >> > > No they didn't - they said that this cannot be done for true dynamic code, > which is true, but obviously doesn't apply to working with > static analysis tools, which is what the question was about. > > Regards, > Stephen > > _________________________________________________________________ > Messenger Café — open for fun 24/7.
