Python 100例题目：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。
程序源代码：
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()
# -*- 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
