Next thing I want to talk board are constants.
So we have variables and we can declare a variable for their boats and we've got the constants.
So if we say Konst name to equites Sarah then we can print this out no problem.
So we say print them to and we run it and we see several.
So as a single Constans is that they are in fact constants so you can't declare and you can't change
the value of whatever you put into your constant soul for our ferryboats case if we want to change is
this variable then we can just say X equals to 46.
And what's happening now is we declared our ability at the top end by saying and just X without the
candle Verba Beckwith's and new variable we put the new variable into R.
So if we print out X again we were half.
We can make it so we print x one time before.
So this X in fact is twenty three.
Then we changed the value of our variable and printed it again.
Below.
And we would see that we get 46 down there.
So we run it we've got 23 this one and then change to the value and then we got 46 so with our constant
we can't change is a value.
So if we want to try it we get an error.
So if we say Man two equals it's
all and we see here this red line indicating an arrow.
And it says constant rabbits can't be assigned a value.
So we have two sets and ones and after that we can't change the value.
Otherwise we get an error and with all variables we just saw we can change the value of them often variable
as often as we like so I could do it again and again.
Doesn't get up at constant can't change.
