Serhiy Storchaka added the comment:
It's cumbersome and burdensome because you need for every nonstandard default value:
1) define a class with __repr__();
2) instantiate a sentinel;
3) check for the sentinel in the function and replace it but an actual value.
class _ExternalAttrDefault:
def __repr__():
return '(stat.S_IRUSR|stat.S_IRUSR)<<16'
_external_attr_default = _ExternalAttrDefault()
def open(self, name, mode='r', external_attr=_external_attr_default):
if external_attr is _external_attr_default:
external_attr = (stat.S_IRUSR|stat.S_IRUSR)<<16
...
Instead of just:
def open(self, name, mode='r', external_attr=(stat.S_IRUSR|stat.S_IRUSR)<<16):
"""
Foo.open(name, mode='r', external_attr=(stat.S_IRUSR|stat.S_IRUSR)<<16)
"""
...
