[Tutor] if-elif-else statements

[Carroll, Barry]

Greetings:  

I have two comments to make.   

First, I recommend renaming your variables to be more clear.  For example:

    #####
    speedlimit = input("Please enter the legal speed limit: ") 
    clockedspeed = input("Please enter the clocked speed limit: ")
    excessspeed = clockedspeed - speedlimit
    #####

Next, you really have two questions to answer, the second of which depends
upon the first:

    1. Was the person speeding?
    2. If so, was the person exceeding 90?

I recommend handling this with nested if statements and calculating the fine
only if the person was actually speeding, like this:

    #####
    if excessspeed > 0:
        fine = 50 + 5 * excessspeed 
        if clockedspeed >= 90:
            fine += 200
        print "The total amount due is", fine
    else:
        print "The speed was legal."
    #####

This should give you the results you want.
