Eric V. Smith added the comment:
Objects/unicodeobject.c has this, at line 14316:
if (PyMapping_Check(args) && !PyTuple_Check(args) && !PyUnicode_Check(args))
ctx.dict = args;
else
ctx.dict = NULL;
and later at line 14348:
if (ctx.argidx < ctx.arglen && !ctx.dict) {
PyErr_SetString(PyExc_TypeError,
"not all arguments converted during string formatting");
goto onError;
}
Because list now returns true for PyMapping_Check, this code thinks the list is
a dict and skips the error.
There's some discussion of PyMapping_Check in issue 5945.
