[issue23318] (compiled RegEx).split gives unexpected results if () in pattern

SilentGhost added the comment: Looks like it works exactly as the docs[1] describe: re.split(r'\s*[+/;,]\s*|\s+and\s+', string) ['Dave', 'Sam', 'Jane', 'Zoe'] You're using capturing groups (parentheses) in your original regex which returns separators as part of a match. [1]

[issue22562] Singleton pattern for namedtuple

Mark Dickinson added the comment: I don't think this is a good idea. Remember that Python classes are themselves mutable objects, so if a library that you happen to import creates a Point namedtuple with fields x and y and class-level modifications (extra attributes, patched-in methods), any

[issue22562] Singleton pattern for namedtuple

R. David Murray added the comment: Agreed. If you want it to be a singleton in your code, use the singleton pattern in your code...but it is hard for me to see why that would be a good idea :) (ie: DRY). Globally, it does not seem to me that there are likely to be any significant number

Leo added the comment: A use case for the singleton pattern arises when - field names are known only at runtime, and - you have a large number of instances with the same field names. An example is the storage of metadata for datasets when a hashable type is needed. I agree
