Given the following code, what would be displayed in outField if the user types $30$ in field$1$ and clicks the button?

$```$

class DemoWindow$($EasyFrame$)$:

def $\_\_$init$\_\_($self$)$:

$"""$Sets up the window and widgets."""

EasyFrame.$\_\_$init$\_\_($self$,$ title $="")$

self.field$1=$ self.addIntegerField$($value $=0,$ row $=0,$ column $=1,$ width $=10)$

self.field$1.$bind$("",$ lambda event: self.calcAnswer$())$

self.outField $=$ self.addIntegerField$($value $=0\mathrm{.}0,$ row $=2,$ column $=1)$

self.addButton$($text $=$ "Compute", row $=3,$ column $=0,$ columnspan $=2,$ command $=$ self.doStuff$)$

def doStuff$($self$)$:

answer $=$ self.field$1.$getNumber$()*2$

self.outField.setNumber$($answer$)$

def calcAnswer$($self$)$:

answer $=$ self.field$1.$getNumber$()/2$

self.outField.setNumber$($answer$)$
