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
