Suggestion by Guido on #868845:

I wrote a simple patch for that. I just copied the definition of type_repr to
a new type_str function, edited the format strings and updated the member
mapping (I checked in another file than casting to reprfunc is okay for a str
func). It compiles and runs just fine, but I’m still learning C, so there may
be things I’ve missed: I don’t know if I have to declare the new function or
something like that. The test suite passes with very few edits.
Guido added this:
> One could even claim that the repr() of a class could be the same
I for one think of repr first as “string form for debugging”, so I like the
angle brackets. My patch leaves __repr__ alone.
If this get approved, I’ll update my patch with doc changes. If there is no
feedback I’ll go to python-ideas.
