Re: True and False Problem

Okay, I arranged it into a class, which I think I did right...

•

ThreeLaws = False

class LawRecite:
def Recite(self):
speaker.Speak(LOR1)
speaker.Speak(LOR2)
speaker.Speak(LOR3)
speaker.Speak(random.choice(LOR4))

LR = LawRecite()

Now if I ask my robot via speech recognition "Do you know the three laws of robotics?" it replies:

•

speaker.Speak ('Yes, I know them well. Would you like me to recite them for you?')
ThreeLaws = True

That part works fine. However, I've noticed that when I try to print if ThreeLaws is True, like so:

•

speaker.Speak ('Yes, I know them well. Would you like me to recite them for you?')
ThreeLaws = True
if ThreeLaws == True:
print 'Let's talk about the three laws of robotics'
else:
print 'Not right now'

I get an attribute error that says that 'NoneType' object has no attribute 'tb_lineno'.

Hmm...I think I understand what wooee meant by two blocks of memory with the same name. What I'm trying to do here is change the variable of ThreeLaws from True to False, but because I mention ThreeLaws = .... twice, that's causing it to be destroyed. Am I right? If so, what's the proper way to change a variable's value? Like a switch, I mean?
