So "at end" or "on normal exit" could be put in any time;
the use of "else" in that context wouldn't go away until 3.0.
The real question is whether it's worth doing at all. I consider
it a fairly minor iss
ething that's meaningful to a human being when
it's printed or otherwise rendered. repr() should be something that
can round trip: that is, if you feed it into eval() it should reproduce
the object.
You can't always achieve either one, especially with very
complex objects, but that's the goal.

The other point to be made here is that, in most cases,
type checks are a design smell. That's not always true, but
it's the first thing to check when you see one.

Providing a method that would translate an arbitrary string into a
valid Python identifier would be helpful. It would be even more
helpful if it could provide a way of converting untranslatable
characters. However, I suspect that the transla
It would ALSO eliminate a whole level of indirection in method
invocation and get rid of the instancemethod, classmethod and
staticmethod wrapper classes. This would be a significant
simplification. If it had been done earlier, it would have eliminated
most of the justification for method attributes (those silly @
things), thus showing that unneeded complexity breeds more unneeded
complexity.

You've got two problems. First, you don't need to encode it; if the
command prompt window displayed your output after encoding it would
display the multi-byte form of your characters. You should just send
it a unicode object.
Second, check the .encoding attribute of the sys.stdout object.

In particular, the decorator problem goes away (the decorators are
irrelevant, and can be ignored) and so does the problem with injecting
a method into an object.
It is, of course, harder to implement, and it would not be backwards
compatible because all the internal wrappers vanish as well. That
makes problems for anyone who is looking through __dict__ to find
particular kinds of method.

The PEPs are also a good source; library changes are all listed in PEP
3008. PEP 361 not only gives the schedule but it also gives a lot of

the process of the import step by step. There are more productive ways

In your situation, it might be a whole lot easier to extract a common

seeing a way of assigning in the middle of an expression because it

Maybe what the OP really wants is the format() method on a string?
That gives a very rich set of override options, at the expense of not
using the print statement/method, including the ability to define your
own formatting language for a class.
