While Loop Ending Early in Python? -


for reason while loop stopping after 2 tries , can't figure out what's wrong... it's supposed ant farm, can choose breed , make new ant, etc. don't understand why it's stopping... here's code: 

import random  class colony(object):     workerants = 0     list = []     temp = []     foodamount = 10     def breedworker(self):         if colony.foodamount < 5:              print "sorry! not have enough food create new worker ant!"         else:                 colony.foodamount -= 5                 colony.workerants += 1                 colony.list.append("ant")     def step(self):         number = 'ant'         number in colony.list:             = ant()             a.forage()             if colony.foodamount > 0:                 colony.foodamount -= 1             if colony.foodamount < len(colony.list):                 number in colony.list[colony.foodamount+1:]:                     ant.health -= 1     def purge(self):         number = 'ant'         number in colony.list:             if ant.health > 0:                 colony.temp.append("ant")         colony.list = colony.temp         class ant(object):       health = 10     def forage(self):         if ant.health == 0:             colony.workerants -= 1         if random.randint(0,100) > 95:             ant.health = 0             print "ant has died horrible accident!"             colony.workerants -= 1         elif random.randint(0,100) < 40:             newfood = random.randint(1,5)             print "ant has found %s food!!" % newfood             colony.foodamount += newfood             elif random.randint(0,100) < 5:             ant.health = 10             colony.foodamount += 10             print "you've found sweet nectar! ant has returned full health , has brought 10 food colony!"         else:             print "ant returned empty-handed!" def main():     queen = colony()     queen2 = ant()     while queen.workerants > 0 or queen.foodamount >= 5:         print "========================================================"         print """         colony has %s ants , %s food, majesty.\nwhat do?\n0: nothing.\n1: breed worker. (costs 5 food.)""" % (queen.workerants, queen.foodamount)         answer = int(raw_input(">"))          if answer != 1 , answer != 0:             print "sorry, invalid input!"         if answer == 0:             queen.step()             queen.purge()         if answer == 1:             print "breeding worker..."              queen.breedworker()             queen.step()             queen.purge()      if queen.workerants <= 0 , queen.foodamount < 5:         print "i'm sorry! colony has died out!"

  1. you don't have constructors (__init__(self, ...)) , not initialize object's properties
  2. in methods call object property self.property, not classname.property; in python explicitly pass instance or class object method, convention should 'self' instance, or 'cls' class.
  3. if want use colony properties in ant object or vice versa, need explicitly pass reference, , store property. sensible create ant colony calling ants.append(ant(self)); ant's constructor should have signature `def init(self, colony):'

ruby on rails - In a controller spec, how to find a specific tag in the generated view? -

i know integration tests preferred need ran in controller test, i'm testing gem injecting html code in view, xhr can't run in feature spec (if can, please explain me how :) ) so rspec controller tests can assert selector present (with capybara) : response.body.should have_selector('#foobar') has_selector? call all method capybara find selector. what want last child of body , assert id in particular. afaik it's not possible have_selector. what : all('body:first-child').first.id.should == '#foobar' however, capybara dsl, defined (more or less): def all(*args) page.all(*args) end and page empty unless use visit it's integrations specs. how can use capybara all method inside rspec controller test ? i can't test right after googling seems trick def page capybara::node::simple.new(response.body) end source
