Hum. It's not easy to read these complex formatting strings when they are written like that. > or > >>>> '%#x' % 255, '%x' % 255, '%X' % 255 > ('0xff', 'ff', 'FF') >>>> format(255, '#x'), format(255, 'x'), format(255, 'X') > ('0xff', 'ff', 'FF') >>>> f'{255:#x}', f'{255:x}', f'{255:X}' > ('0xff', 'ff', 'FF') I really prefer when the same kind of the formating strings are written on the same line. I really like this example. Short, obvious, easy to read. I have a prefererence for an example using a variable name rather than a number literal. It's more common to manipulate variables than number literals. If you use a variable, please use a variable name longer than "n" to get more readable example. Otherwise, it's not obvious what is in the variable name in "{n:x}": is "n" the variable? is "x" the variable? In short, I suggest this example: >>> value = 255 >>> '%#x' % value, '%x' % value, '%X' % value ('0xff', 'ff', 'FF') >>> format(value, '#x'), format(value, 'x'), format(value, 'X') ('0xff', 'ff', 'FF') >>> f'{value:#x}', f'{value:x}', f'{value:X}' ('0xff', 'ff', 'FF') Note: Ezio, do you prefer format(value, 'x) for '{:x}'.format(value)? > 2) add a direct link to > https://docs.python.org/3/library/string.html#format-examples where there are > already some examples (more can be added if needed); IMHO it's ok to add formatting examples to bin/hex/oct. Using your compact example, it's not going to make the doc too long. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26506> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
