Another big problem with tensors is the covariance and contravariance. Usually in informatic you denote the covariance with the subscript operator, that on paper is written as subscript. Contravariant index on the contrary is a superscript. Not sure how a programming language can easily represent it. Maybe PEP 472 can help here? _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/O3PEI2IGWIO37FD35JXGI3Z4HKEC4Z5T/ Code of Conduct: http://python.org/psf/codeofconduct/
