Re: [Tutor] Question

[zubair alam]

what exactly you want to do by

[1,2,3] = "Anything"


the above code is called unpacking of sequence, so there must be some
variable on left side of assignment operator.
but you have list of integers, why?

[Tutor] class data member and objects of class in python

[zubair alam]

i am learning how a __class__ data member behaves in python as compared to
static data member in java, but following code is throwing error


class PizzaShop():
pizza_stock = 10
def get_pizza(self):
while not PizzaShop.pizza_stock:
PizzaShop.pizza_stock -= 1
yield "take yours pizza order, total pizzas left
{}".format(PizzaShop.pizza_stock)

mypizza_shop = PizzaShop()
pizza_order = mypizza_shop.get_pizza() # iterator is obtained
print "a pizza pls!! {}:".format(pizza_order.next())
print "a pizza pls!! {}:".format(pizza_order.next())

output:
Traceback (most recent call last):
  File "/home/scott/pythonfiles/core_python/pizza.py", line 10, in 
print "a pizza pls!! {}:".format(pizza_order.next())
StopIteration


don't know where i am doing mistakeany help will be appreciated... i
have other questions on based on this class

print "{}".format(repr(domino_pizza_store.next()))

mypizza_shop.pizza_stock = 10

domino_pizza_store = mypizza_shop.get_pizza()
print "{}".format(repr(domino_pizza_store.next()))


can't we again use the same object mypizza_shop once its generator is
exhausted
