Simon Sauter
Does python see it this way in the buged edition
Does it see it as if there are 2 difreant boats
one as in boat input
And one as in boat * 3000000
If its wrong can you explaine what the computer sees it as

Answer 3

When you use
boat = boat * 3000000
the value of boat is overwritten. Since you don't need the original value anymore that is no problem in this case.
Alternatively you could create a new variable. E.g.
income = boat * 3000000
In this case you have to use income instead of boat in the conditionals. The advantage is that if you do it like this you still have the original value stored in the boat variable. So whenever you might need the original value again you should create a new variable.
If you just use
boat * 3000000
the calculation is executed, but the result is not saved.
