I don't have a particularly strong opinion here, other than to say I'm not sure I like the upper case "I". It looks far too much like a lower case "L" in the font I'm using here, which makes me think of C's "long", so it's easy to confuse. So of the two options, I prefer !f, !d, !i over !f, !i, !I.
Thank you. The upper case "I" is used in many formatting strings: struct, memoryview, array, PyArg_Parse, Py_BuildValue, and there are no plans for !l to confuse. But I follow you suggestion if there would not be other arguments. Also, %d is more common than %d, so using !d for lossy conversion to integer is understandable. Maybe we even repurpose rarely used %i in printf-style formatting for lossless conversion to integer.
