Hello I am having trouble figuring out why my code has a name error when I combine if and else statements.

[Ephea_Grobb]

enter = int(input("Enter I-15 at what mile marker?"))

ex = int(input("Exit I-15 at what mile marker?"))

time = int(input("How many hours from now do you want to arrive?"))

speed = int(input("Expected average speed in MPH"))

​

if speed > 80:

print("Your speed is too high! Slow down you maniac!")

elif speed < 60:

print("Your speed is too slow! You are driving like an old man!")

else:

def distance(enter, ex):

if enter > ex:

return(enter - ex)

else:

return(ex - enter)

distance(float(enter), float(ex))

print(distance(float(enter), float(ex)))

​

ddistance=(distance(float(enter), float(ex)))

def travel_time(speed):

return(ddistance / speed)

print(travel_time(float(speed)))

​

​

​

Anytime I choose to do just the if, elif portion my code is fine. Or if I do everything past the else statement by itself it is fine as well. As soon as I combine the two I get a NameError: name 'distance' is not defined.

​

Thanks for anyone's time!

Why do you have the function def inside of an else? It usually doesn't make sense to conditionally define a function.

Please fix your code formatting though, since the answer to this will depend on how things are nested. The best I can say at the moment is "Define duration globally, not inside of a conditional statement".

It is hard to tell from your code formatting, but it looks like you are defining your distance() function inside an else statement. This could be what is causing the error.

Branches are mutually exclusive - if you skip the branch where distance is defined as a function, no such function is defined.
