So how to solve this problem ???

Answer 1

Easiest way to run a Python module in PyDev is just pressing F9 when focusing the editor.

The getting started guide has a chapter dedicated to that which gives more hints on running modules with PyDev: http://pydev.org/manual_101_run.html (ideally you should follow it from the beginning: http://pydev.org/manual_101_root.html)
