This question assesses Block $2$ Part $4.$ It assumes an understanding of binary notation and truth tables $($Block $1$ Part $1).$

Study the following function.

def truth$\_$value$($integer$)$:

$"""$Convert an integer into a truth value."""

# Convert $0$ into False and all other integers,

# including $1,$ into True

if integer $==0$:

truth$\_$value $=$ False

else:

truth$\_$value $=$ True

return truth$\_$value

Now, write a function that goes in the opposite direction of the truth$\_$value$()$ function. This new function should convert a truth value into an integer. In particular, True should be converted into $1$ and False into $0.$ Name the new function integer$\_0\_$or$\_1().$
