Summary: print >> f, "Hello" produces no error: normal?

Initial Comment:
When using
  print >> f, "Hello"
on a file f opened for reading, no exception is raised.  Is this normal?

This situation has to be contrasted with
  f.write("Hello")
which raises an exception.

Details with Python 2.5 (r25:51908, Sep 24 206) on OS X 10.4.8 / darwin 8.8.0:

In [1]: f=open("start.01")
In [2]: f.write("Hello")
<type 'exceptions.IOError'>: [Errno 9] Bad file descriptor
In [3]: print >> f, "Hello"
In [4]: f.close()

NB: file f is not modified, despite the "print" statement yielding no error, above.

If this happens, it's a bug. Though it doesn't seem to occur under Linux
here.
