本文实例讲述了python列表操作之extend和append的区别。分享给大家供大家参考。具体如下:

li = ['a', 'b', 'c'] 
li.extend(['d', 'e', 'f'])
print li 
print len(li)
print li[-1] 
li = ['a', 'b', 'c'] 
li.append(['d', 'e', 'f'])
print li 
print len(li)
print li[-1] 

Copy after login

运行结果如下:

['a', 'b', 'c', 'd', 'e', 'f']
6
f
['a', 'b', 'c', ['d', 'e', 'f']]
4
['d', 'e', 'f']

Copy after login

希望本文所述对大家的Python程序设计有所帮助。
