Oh ok, in this case, you need something smarter like: mode = 'a' if not stat.S_ISCHR(os.stat(filename).st_mode) else 'w' fp = open(filename, mode) or something like (emulate append mode, but catch ESPIPE): fp = open(filename, 'w') try: fp.seek(0, os.SEEK_END) except OSError as exc: if exc.errno != errno.ESPIPE: raise ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27805> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
