=== 1.编写 斐波那契数列 的初始子序列 ===
 <code>a, b = 0,1
    while a < 10:
    print(a)
    a, b= b, a+b</code>
或者
 <code>def fab(max): 
    n, a, b = 0, 0, 1 
    while n < max: 
        print b 
        a, b = b, a + b 
        n = n + 1
 fab(5)</code>

=== 2.今天吃什么 ===

 <code> values = list(range(1,11)) + 'Jack Queen King'.split()  #列表,list(range...
  suits = 'diamond clubs hearts spades'.split()           #[diamond,clubs,hearts,spades]
  deck = ['%s of %s'%(v, s) for v in values for s in suits]  #两个for，最终是个列表
  
 <code> from pprint import pprint  #自动换行
  pprint(deck[:12])          #只选12张（按顺序）显示如下</code> 

['1 of diamond',
