What's the barbershop problem?
Why do you need three classes?

The formatting here is completely messed up. If you are posting using
Gmail, you need to ensure that your email uses no formatting (no bold,
no colours, no automatic indentation etc), or else Gmail will mangle the
indentation of your code, as it appears to have done above.
My wild guess is that what you probably want is something like this:
import random
import time
class Barber(object):
def __init__(self, name):
self.workingEvent = Event() # What is Event?
self.name = name
def sleep(self):
self.workingEvent.wait()
def wakeUp(self):
self.workingEvent.set()
def cutHair(self, customer):
# Set this barber as busy.
self.workingEvent.clear()
template = '{0} is having a haircut from barber {1}\n'
print template.format(customer.name, self.name)
HairCuttingTime = random.randrange(0, 5)
time.sleep(HairCuttingTime)
print '{0} is done\n'.format(customer.name)
tony = Barber('Tony')
fred = Barber('Fred')
george = Barber('George')
# and then what?
Notice that we have *one* class and three instances of that class. I've
given them individual names so they're easier to distinguish.
Please ensure you reply on the mailing list.
