I think having math.pi is just for backward compatibility. We all use tau now, I assume. That's why the true definition is:
pi = math.tau/2 :-) ... and yes, as someone else comments, adding tau was a bit whimsical in the spirit of 'import antigravity' and the line.

But this deserved the whole PEP and was added as a feature in 3.6. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
