python实现类的静态变量用法实例

__author__ = 'Administrator'
class CaptchaImage:
  def queue(self,arr=list()):
    return arr
  def InsertCode(self,code):
    self.queue().append(code)
if __name__=='__main__':
  c = CaptchaImage()
  c.InsertCode(1)
  b=CaptchaImage()
  b.InsertCode(2)
  print(b.queue())
  print(c.queue())

代码执行输出结果为：

[1, 2]
[1, 2]
