Hello. I am stuck on a simple piece of code. For some reason it keeps saying it can't call the Str object. Im also unsure on how to float the data to 2 decimal points (i don't know where the 2.f% should go.) The task is to make a taxi fare calculator based on the given distance. It costs £1.20 to start with, for every km up to 10 its 70p and over 10 an extra 30p per km. Thank you.

``````def taxiFare():
distance = input("How long is the journey to your desired destination?")
start = 1.20
if distance <=10:
print "the total journey price will be"  (distance*0.7)+start
elif distance >10:
print "the total of the journey will be" (((distance - 10)*30)+8.20)``````

When printing multiple things, seperate them with a comma. For instance:

``````distance = 15
print "The distance is", distance
#Output: The distance is 15``````

However, there's a better was to do it:

``````distance = 2.873430192
print "The distance is %.2f miles." % distance
#Output: The distance is 2.87 miles.``````

Just put the %d or %f or %.2f or %s or whatever inside of the string, then follow the string with a %, then put your variable there. If you have more than on thing you want to put in a string, put your variables as a tuple at the end.

``````a = 15
b = 20
print "The two variables are %d and %d." % (a,b)
#Output: The two variables are 155 and 20.``````

There are some other neat tricks you can do with this, but I'll leave that to you to find out if you care.

Btw, you don't just have to list a variable at the end, you can do operations to it, too.

``print "The total journey price will be %.2f" % distance*0.7+start``

You need to check your calculations. You are charging the poor customer 30 Pounds per km for traveling a distance above 10 km. You really want to charge him 1 Pound (0.7+0.3) per km. Also, you need to add a 10 mile short price to the distance-10 long distance price
