Exercise 1.9: inclusive or exclusive range about practical-python HOT 5 CLOSED

Many fundamental parts of Python including slices and ranges require one to think about the difference between inclusive and exclusive ranges. The ambiguity in the description might be intentional ;-).

While I do agree that thinking about ranges is important, the solution resulting in 49 months for a exercise that asks for a duration of 4 years does not seem intended or helpful to me.

You may be right. Sometimes things for the in-person setting might not translate to self-study. I will make a fix.

It seems like the problem is the constants rather than the inequalities. If someone made extra payments for the first year, starting in month 1 and ending in month 12 would make the most sense. Without the constants given I would have used start_month=49 and end_month=49+48-1 to start with the first payment of the fifth year and continue for 48 months.

Oh, that's a good observation. Will look at it again.
