In random.py:randrange

  File "/usr/lib/python3.7/random.py", line 200, in randrange
    raise ValueError("empty range for randrange() (%d,%d, %d)" % (istart, istop, width))
ValueError: empty range for randrange() (3,3, 0)


should be "empty range for randrange() (3, 3, 0)"

Cheryl, do you want to neaten-up this error message?  

It is triggered by randrange(3, 3).

I previously close this issue is because not sure if someone rely on exception string to do something, should we consider this?

I think this is a valid issue since error messages have been modified in the past. I am not sure if this will be backported to 3.7 though.

We usually don't backport exception message changes, for the reason given, unless the content is wrong or misleading.  Unless Raymond says otherwise, I think the backport should be closed as too trivial and this issue closed as fixed.

Assigning to Raymond regarding the question about the backport.

I concur with Terry that no backport is warranted.
