I don't see any changes handling the following: $ git annotate tools/perf/scripts/python/export-to-sqlite.py | grep ">> sys" 564b9527d1ccf (Adrian Hunter 2017-08-03 11:31:28 +0300 64) print >> sys.stderr, "Usage is: export-to-sqlite.py [] [] []" 564b9527d1ccf (Adrian Hunter 2017-08-03 11:31:28 +0300 65) print >> sys.stderr, "where: columns 'all' or 'branches'" 564b9527d1ccf (Adrian Hunter 2017-08-03 11:31:28 +0300 66) print >> sys.stderr, " calls 'calls' => create calls and call_paths table" 564b9527d1ccf (Adrian Hunter 2017-08-03 11:31:28 +0300 67) print >> sys.stderr, " callchains 'callchains' => create call_paths table" $ echo 'import sys ; print >> sys.stderr, "Usage is: exported-sql-viewer.py { | --help-only}"' | python2 Usage is: exported-sql-viewer.py { | --help-only} $ echo 'import sys ; print >> sys.stderr, "Usage is: exported-sql-viewer.py { | --help-only}"' | python3 Traceback (most recent call last): File "", line 1, in TypeError: unsupported operand type(s) for >>: 'builtin_function_or_method' and '_io.TextIOWrapper'. Did you mean "print(, file=)"? They are best handled via conversion to sys.stderr.write() since sys is already imported. Tony
