Python 练习实例42
题目:学习使用auto定义变量的用法。
程序分析:没有auto关键字,使用变量作用域来举例吧。
实例
#!/usr/bin/python # -*- coding: UTF-8 -*- num = 2 def autofunc(): num = 1 print 'internal block num = %d' % num num += 1 for i in range(3): print 'The num = %d' % num num += 1 autofunc()
以上实例输出结果为:
The num = 2 internal block num = 1 The num = 3 internal block num = 1 The num = 4 internal block num = 1
