Echoing evaluation result in embeded Python?

[Kim Jeong Ju]

When you run Python in console mode, you can see result string after
evaluation.

>>> 3 + 4
7
>>> dir
<built-in function dir>

But Embeded Python doesn't show its result string anymore..
You should specify 'print' command to see the result as in consol mode.
>>> 3 + 4
>>> dir
>>> print 3 + 4
7
>>> print dir
<built-in function dir>

Why this behavior happens?
Are there any way to let Python echoing result automatically in embeded
version?

Thanks.
