python实现类的静态变量用法实例

本文实例讲述了python类的静态变量用法。分享给大家供大家参考。具体分析如下：

这里使用静态变量目的是在类中实现一个静态的队列，这里用数组实现，任何时候插入到队列中的数据不会和类的实例有直接关系。

__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]

希望本文所述对大家的Python程序设计有所帮助。
