The final entry is identical to the second to last, because ints have no concept of -0. If you used a float literal, it would match the first two: >>> -0.-1j (-0-1j) I suspect the behavior here is due to -1j not actually being a literal on its own; it's interpreted as the negation of 1j, where 1j is actually 0.0+1.0j, and negating it flips the sign on both the real and imaginary component. >From what I can read of the grammar rules, this is expected; the negation >isn't ever part of the literal (minus signs aren't part of the grammar aside >from exponents in scientific notation). >https://docs.python.org/3/reference/lexical_analysis.html#floating-point-literals If this is a bug, it's a bug in the grammar. I suspect the correct solution here is to include the real part explicitly, as 0.0-1j works just fine. ---------- nosy: +josh.r _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40269> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
