题目：模仿静态变量(static)另一案例。

程序分析：演示一个python作用域使用方法

程序源代码：

#!/usr/bin/python
# -*- coding: UTF-8 -*-
class Num:
 nNum = 1
 def inc(self):
 self.nNum += 1
 print 'nNum = %d' % self.nNum
if __name__ == '__main__':
 nNum = 2
 inst = Num()
 for i in range(3):
 nNum += 1
 print 'The num = %d' % nNum
 inst.inc()

以上实例输出结果为：

The num = 3
nNum = 2
The num = 4
nNum = 3
The num = 5
nNum = 4
