代码如下：
1 fruits = [‘apples‘, ‘oranges‘, ‘pears‘, ‘apricots‘] 2 change = [1, ‘pennies‘, 2, ‘dimes‘, 3, ‘quarters‘] 3 4 # this first kind of for-loop goes through a list 5 for number in the_count: 6 print "This is count %d" % number 7 8 # same as above 9 for fruit in fruits: 10 print "A fruit of type: %s" % fruit 11 12 # also we can go through mixed lists too 13 # notice we have to use %r since we don‘t know what‘s in it 14 for i in change: 15 print "I got %r" % i 16 17 # we can also build lists, first start with an empty one 18 elements = [] 19 20 # then use the range function to do 0 to 5 counts 21 for i in range(0, 6): 22 print "Adding %d to the list." % i 23 # append is a function that lists understand 24 elements.append(i) 25 26 # now we can print them out too 27 for i in elements: 28 print "Element was: %d" % i
运行结果：
相关内容：
1.append
用于在列表末尾追加新的对象： >>> lst = [1, 2, 3] >>> lst.append(4) >>> lst [1, 2, 3, 4]
2.count
统计某个元素在列表中出现的次数：
>>> [‘to‘,‘be‘,‘or‘,‘not‘,‘to‘,‘be‘].count(‘to‘)
2
>>> x =[[1,2],1,1,[2,1,[1,2]]]
>>> x.count(1)
2
>>> x.count([1,2])
1
3.extend
在列表的末尾一次性追加另一个序列中的多个值
