Python program

i want to Design a program that calculates and displays the number of miles per hour over the speed limit that a speeding driver was doing. The program should ask for the speed limit and the driver’s speed. Validate the input as follows:  The speed limit should be at least 20, but not greater than 70.  The driver’s speed should be at least the value entered for the speed limit (otherwise the driver was not speeding).

I fell there is something wrong with my code, can someone fix it for me, and tell me what was the wrong things This is my Code:-

Declare Integer speedLimit, speed, minSpeed, maxSpeed, overSpeed

Module Module1

def main(): speedLimit = int(input("Please enter speed limit, if it's between 19 and 71 mph, then press enter: ")) print("You entered: ", speedLimit)

while(speedLimit < 20 and speedLimit < 70):
    if (speedLimit < 20):
        print("Sorry, speed limit less than 20 mph. Try again ")
    elif(speedLimit > 70):
        print("Sorry, speed limit more than 70 mph.Try again.")
    else:
        ("ddjid")


driverSpeed = int(input("How fast are you driving: "))

if (driverSpeed > speedLimit):
    print("Alert! You are driving over the speed limit")
else:
    print("You are driving at or under the speed limit.")

main()

Hello Hanan,

first of all your code should be calling main() in that way:

if __name__ == "__main__":
    main()

Second you should move your input statement in the while loop like this: 

def main():
   speedLimit = 0
   while(speedLimit < 20 or speedLimit > 70):
       speedLimit = \
           int(input("Please enter speed limit, if it's between 19 and 71 mph, then press enter: "))
       print("You entered: ", speedLimit)
       if (speedLimit < 20):
            print("Sorry, speed limit less than 20 mph. Try again ")
       elif(speedLimit > 70):
            print("Sorry, speed limit more than 70 mph.Try again.")

Third your while statement was not correct: I corrected it in the above version of the code. The rest of your code should work fine if you make these corrections. I hope that helps.
