PR 26160 adds support of %d, %i, %u, %o, %x, %X, %f, %e, %g, %F, %E, %G. What is not supported: * Formatting with a single value not wrapped into a 1-tuple (like in "%d bytes" % size). The behavior is non-trivial, it needs checking whether the value is a tuple or a mapping. It would require adding more opcodes and AST nodes and generating complex bytecode. * Mapping keys (like in "%(name)s"). They are rarely used, and if used, it is not performance critical. * Precision for integer formatting. Precision is not supported in new-style formatting of integers, and it is not trivial to reproduce this behavior. * Variable width and precision (like in "%*.*s"). It is possible to support them, but the code would be pretty complex, and the benefit is small, because this feature is rarely used and is not performance critical. * Format code %c. It is relatively rarely used. * Length modifiers "h", "l" and "L" (like in "%ld"). They ignored in Python and I did not see them in real code. While supporting them is easy, it would requires adding more than one line of code, it is not worth it. ---------- priority: low -> normal _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue28307> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
