[issue27498] Regression in repr() of class object

[Guido van Rossum]

New submission from Guido van Rossum:

In Python 3.6, the repr() of a class includes its memory address.

This is going to cause a lot of problems for tests in 3rd party code that expects the nice and clean <class '__main__.C'> instead of <class '__main__.C' at 0x7feb0360f568>.

I understand the desire to provide more clarity in case somehow two class objects created at different times have the same name -- but I'm not sure I like to rub the hex address in the user's face all the time.

Can we please roll this back or think about a better way to reveal this that won't break so many 3rd party tests?
