Mailman 3 [issue30456] 2to3 docs: example of fix for duplicates in second argument of isinstance has superfluous parentheses - docs

24 May 2017

      New submission from Eli_B:

The documentation says isinstance(x, (int, int)) would be fixed to isinstance(x, (int)). The fix is actually isinstance(x, int).

I propose the following text instead:
"
2to3fixer:: isinstance

Fixes duplicate types in the second argument of :func:`isinstance`.  For example, isinstance(x, (int, int)) is converted to isinstance(x, int) and isinstance(x, (int, float, int)) is converted to isinstance(x, (int, float)).
