In the few cases where isinstance(data, file)
is used, I actually think such behaviour should be deprecated: force the user to call foo(open(f).read())
instead of foo(open(f))
.

The code in lattice_polytope.py
is already deprecated anyway by #15240...

 Resolution set to fixed
 Status changed from positive_review to closed
Note: See
TracTickets for help on using
tickets.
In Python 2,
isinstance(f, file)
is not equivalent toisinstance(f, io.IOBase)
.I do give positive_review to the change from
file()
toopen()
.
