Because they’re in the standard library, and convenient. I would never use a third-party package just for some syntactic sugar.
I don't understand the inconvenience. Isn't it just adding `attrs` to requirements.txt once for the whole project, and then you get more features ever after?
Notable parts of this release (IMO): * Data classes ( https://docs.python.org/3.7/library/dataclasses.html ) * New breakpoint() builtin ( https://docs.python.org/3.7/library/functions.html#breakpoin... ) * Dictionaries preserve insertion order. (Implemented in 3.6, but now is part of the official spec.)
That is a terrible decision. Call me a heretic.
Yes, I know it's a side effect of bringing in the bitmap index version from PyPy. Yes, I am aware that collections.OrderedDict is now an alias to internal dictionary type. And yes, I do understand that randomising the key traversal order could incur a performance penalty.
But a dictionary where keys come out in anything other than unspecified order is a subtle trap just waiting to blow up. I personally prefer golang's map behaviour - keys are always in unspecified order, and the order is different even between calls.
Hey, does anyone know where to find information about how python's releases are structured? For example, 3.6 exists and 3.7 is released. Without looking at the release details, should I be upgrading? Should I assume that it will break stuff, or assume that it won't, or should I make no assumptions? Etc...
