I'm trying to figure out how to get the value of a variable
that's constantly getting updated, but only get the new
value, once it has changed.
I have a module where I register a call back to a function
in the code I'm working on. This function gets updated continuely.
ie....
x = ''
def myfunc(event)
global x
x = event
if you where to do a while loop, you would end up with something like...
while 1:
print x
if x == 'stop':
break
1,1,1,1,1,1,2,2,2,2,2,3,3,3,3,3,
if you where to do a nested while, you would get....
while 1:
print x
while x != x:
print x
if x == 'stop':
break
if x == 'stop':
break
1,2,3,4,5
but it of coarse just spins the loop and processor loads pegs out.
If someone could point me in a direction, I'd appreciate it.
Thanks
