TKinter Entry question

[vector]

Q1 can I put some pre text in the entry box?. How?
Q2 how do I know when/if to get the users entry?
		does Python/tk set a flag.
Im trying to achieve a simple GUI(within a frame of other buttons etc)
entry box, that i can shove some pre text in(default) but allow a user
to modify.
