I had this code:

    import color
    Block_Color_Q = input('Robot Color: Red(1) Blue(2) Green(3) Yellow(4) Orange(5)')
    if Block_Color_Q == 1:
        Block_Color = color.red
    elif Block_Color_Q == 2:
        Block_Color = color.med_light_blue
    elif Block_Color_Q == 3:
        Block_Color=color.lime
    elif Block_Color_Q == 4:
        Block_Color = color.dandilion_yellow
    elif Block_Color_Q == 5:
        Block_Color = color.orange

Later in my code I had:

print(Block Color)

What SHOULD happen is if they entered 3, than it would print(color.lime) but only half the time it works, the other half an error pops up saying

Error:
Block_Color does not exist

Why????

If you run this in Python 3.x, you will always get that error. In Python 3.x, input returns a string.

In Python 2.x, this should work if the user types the correct thing in. However, if they don't, you'll get that error.

I would add a print(repr(Block_Color_Q)) to the program, to show you exactly what the user entered and how the program interpreted it.

Ya so according to ichabod801 if you are using python 3.x you might what to do something like this

x = int(input("Something"))

Here x will be an int. Because you are testing for an int you code will probably work
