Question Details
I need my code to make sure that if the user gets the error message, to have the program ask them to re-enter valid information., and then prompt the user to enter their speed limit and their speed.... am stuck here am new to Python.
This is what I have:

speedlimit = int(raw_input("What is the speed limit? "))
driverspeed = int(raw_input("What is your speed? "))

if 20 <= speedlimit <= 70:
if driverspeed < speedlimit:
print "You're not speeding."
else:
milesover = driverspeed - speedlimit
print "You're going ", milesover, " mph over the limit."
else:
print "Error: speed limit not in valid range."

Explanation / Answer

Please rate - Thanks


Not sure if you mean to loop only when the last error occurs or when any of the errors you noted occurs. So, here are both scripts for you to choose:

 

script #1:
 

# Loop over the speed limit validation only.
#
while True:
    speedlimit = int(raw_input("What is the speed limit? "))
    if 20 <= speedlimit <= 70:
        break
    print "Error: speed limit not in valid range."
#
# No more loop here.
#
driverspeed = int(raw_input("What is your speed? "))
if driverspeed >= speedlimit:
    milesover = driverspeed - speedlimit
    print "You're going ", milesover, " mph over the limit."
else:
    print "You're not speeding."


script #2:

# Loop when any one of the noted errors occurs.
#
while True:
    speedlimit = int(raw_input("What is the speed limit? "))
    driverspeed = int(raw_input("What is your speed? "))
    if not( 20 <= speedlimit <= 70 ):
        print "Error: speed limit not in valid range."
    elif driverspeed >= speedlimit:
        milesover = driverspeed - speedlimit
        print "You're going ", milesover, " mph over the limit."
    else:
        print "You're not speeding."
        break

Let me know if you have any question - I'll rush over a fix.

 

/update - Minor simplification to the script #1. No change on functionality.
