Answer 2

HonFu LOL... We typically have a good sense for the strengths and weaknesses of a new developer joining one of my teams before he or she starts working in the code.

I've not encountered problems stemming from Python because we simply don't do any serious development with Python.

The reasons for not doing any serious development in Python stems from the risks associated with performance, lack of familiarity in a development workflow that we can trust to meet our needs, the uncertainty of Python's direction as a language and community, and the lack of desire to force ourselves to conform to PEP for best practices.

Python doesn't have constants but if you want others to know it's a constant you should name it LIKE_THIS

Answer 4

The whole PEP Pythonic Zen coding thing where everyone just agrees to drink the Kool-aid and follow the conventions and accept fundamental limitations is where I typically struggle with taking this cult, eh hem... language seriously. Just my 2 cents.

Answer 5

The only thing that comes to mind is a tuple, which may not be what you are looking for.

Answer 6

David Carroll, do you encounter problems stemming from these limitations/liberations in your job life?

My first thought would be: What's with the new guy on the team? Who somehow got hired but noone knows yet how good he/she really is?

Answer 7

No, there's no const in Python.

Answer 8

I suppose that's part of the 'we're all grownups here attitude' assuming that a visual cue should be enough to stop you from doing nonsense.
