[issue6396] '' % object() raises TypeError

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

The original bug claim is invalid. But the following (3.2.0, winxp) strike me as a bug, hence the title change

>>> class A: pass

>>> '' % A()
''
>>> '' % object()
...
TypeError: not all arguments converted during string formatting

More difference:

>>> '%(a)s' % object()
...
TypeError: format requires a mapping
>>> '%(a)s' % A()
...
TypeError: 'A' object is not subscriptable
