Hi, I proposed a second change to restore the "U" open() mode (universal newlines): https://github.com/python/cpython/pull/18767
Again, it's only kept in Python 3.9 to ease migration from Python 2, but will be removed in Python 3.10. By the way, I also added a new "You should check for DeprecationWarning in your code" section to "What's New In Python 3.9" document, to strongly advice users to check for deprecation warnings in their code: https://docs.python.org/dev/whatsnew/3.9.html#you-should-check-for-deprecationwarning-in-your-code Victor Le mar. 18 févr. 2020 à 12:37, Victor Stinner <vstin...@python.org> a écrit : > > Hi, > > I created an issue: > > "Keep deprecated features in Python 3.9 to ease migration from Python > 2.7, but remove in Python 3.10" > https://bugs.python.org/issue39674 > > And proposed a first pull request to add again collections.Mapping: > > https://github.com/python/cpython/pull/18545 > > Victor _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/KT4B2C3EFEB6MXG55OHGCKN7CRVKI4SX/ Code of Conduct: http://python.org/psf/codeofconduct/
