Python 练习实例43
Python 100例题目：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：
实例
#!/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()
# -*- 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
