well if you have something like this:
miles = int("5")
gallons = 1
the " " around miles turns miles into a string. And you just can't do that.
Here's a proper example of an mpg calculator:
miles = int( raw_input("Miles driven: "))
gallons = int( raw_input("Gallons used: "))
print "Your Miles Per Gallon: ", miles/gallons
although converting them to float would allow you a little more accuracy in
your measurements. But if you're just looking at whole number values, that
should be fine.
