Help understand loops

[tonycstech]

I have 3 loops that i am confused about.

tkinter.mainloop()

Is this loop specifically for tkinter module and it will run independent from the rest of the code ?

mainloop()

is this main loop that runs independent of any modules that are currently running ?

while 1:
    code here

What kind of loop is that then ?

How to exit or terminate tkinter.mainloop() or mainloop(), with a break ? Where in the code would i place it ?
Thanks !
