An interactive introduction to programming in Python, for human beings and whoever else
In Virginia, there are two punishments for speeding in a car: a speeding ticket (bad), or reckless driving (worse!). We’re going to build a robot to warn people about their driving habits.
Ask the user how fast they are going, print out their speed, then print out their status according to these guidelines:
Reckless driving(e.g. 50 in a 30 zone)
Note: You cannot be charged with both reckless driving and speeding. If you’re going fast enough to be reckless, it’s just reckless driving.
The code I’ve given you randomly picks a speed limit1 and prints it to the screen. After that, it’s all up to you! Start by asking the user how fast they’re going.
 Technically the code imports some other code that lets you use random numbers, then picks a number between 15 and 65, going in steps of 5 (15, 20, 25, 30…)
import random random.seed(6779) speed_limit = random.randrange(15, 66, 5) print("The speed limit is", speed_limit)
inputto ask how fast the user is going
speed = input("How fast were you going?")will save the user’s input to a variable called
inputalways gives you a string, so you’ll need to use
int()to convert the user’s input to an integer. If we don’t, you can’t compare it to other numbers! That’ll probably give you an
unorderable typeserror about
speedto an integer every time you compare - like
int(speed) > speed_limit- or you can convert just once and overwrite the original value, like
speed = int(speed)
elifwhen checking the speed.
elifthat works, it doesn’t run any of the other options. The order that you check in will probably be important!
