同一python程序，为何在IDLE和PyCharm上运行，会得到两种结果

[py_66]

同一程序，在IDLE和PyCharm上运行结果如下：


附代码：

class Person:
  '''Represents a person.'''
  population = 0
  def __init__(self, name):
    '''Initializes the person's data.'''
    self.name = name
    print '(Initializing %s)' % self.name
    # When this person is created, he/she
    # adds to the population
    Person.population += 1
  def __del__(self):
    '''I am dying.'''
    print '%s says bye.' % self.name
    Person.population -= 1
    if Person.population == 0:
      print 'I am the last one.'
    else:
      print 'There are still %d people left.' % Person.population
  def sayHi(self):
    '''Greeting by the person.
    Really, that's all it does.'''
    print 'Hi, my name is %s.' % self.name
  def howMany(self):
    '''Prints the current population.'''
    if Person.population == 1:
      print 'I am the only person here.'
    else:
      print 'We have %d persons here.' % Person.population

swaroop = Person('Swaroop')
swaroop.sayHi()
swaroop.howMany()

kalam = Person('Abdul Kalam')
kalam.sayHi()
kalam.howMany()

swaroop.sayHi()
swaroop.howMany()

在IDLE中执行时因为解释器没有关闭所以没有触发 __del__ 在最下面加两句就一样了。 del(kalam) del(swaroop)

嗯，现在一样了，谢谢
