I solved the problem by emulating key press event using keyboard.press and listen the same event using keyboard.Listner() both are present in keyboard library.So I didn't use pygame functions to listen the event. Thanx everyone for ur help.

In pygame you can add events to the event queue by doing:

newevent = pygame.event.Event(type, **attributes) #create the event
    pygame.event.post(newevent) #add the event to the queue

Where type is the type of the event (a numerical constant) and **attributes a keyarg list of attributes, also predefined constants.

All these constants are defined in the pygame.locals module. pygame event docs and pygame key docs list all of them.

So if you want to simulate the press of the 'a' key for example, the code would be:

newevent = pygame.event.Event(pygame.locals.KEYDOWN, unicode="a", key=pygame.locals.K_a, mod=pygame.locals.KMOD_NONE) #create the event
    pygame.event.post(newevent) #add the event to the queue

KEYDOWN is the constant corresponding to the keydown event.
unicode is the unicode representation of the pressed key.
key is a constant associated to the pressed key.
mod is a constant representing a modifier (if the button is pressed while also SHIFT or CAPS_LOCK is pressed, for example).

Hope it helps.
