mistercrunch opened a new issue #5565: SIP-2 Deprecate support for python <3.6 URL: https://github.com/apache/incubator-superset/issues/5565 # SIP-2 Deprecate support for python <3.6 ## Motivation There's extra cost in maintaining multiple versions of python: * longer build times (travis build matrix does 2.7 and 3.x now) * can't take full advantage of nice py3 features like async/await, f-strings and much more * intricate bugs ## Proposed Change * remove buid env from tox build matrix * remove <py3.6 specific code, like `from __future__` imports * start recommending f-strings instead of `str.format()` * add notes/instructions in `UPDATE.md` * update the installation docs ## New or Changed Public Interfaces People not running >=py3.6 will need to change their installation scripts. ## Migration Plan and Compatibility N/A ## Rejected Alternatives Supporting py2.7 forever
