本文实例讲述了python字典get()方法用法。分享给大家供大家参考。具体分析如下:

如果我们需要获取字典值的话,我们有两种方法,一个是通过dict['key'],另外一个就是dict.get()方法。

这里给大家分享的就是字典的get()方法。

这里我们可以用字典做一个小游戏,假设用户在终端输入字符串:"1"或者是"2"或者是"3",返回对应的内容,如果是输入其他的,则返回"error"

>>> info = {'1':'first','2':'second','3':'third'}
>>> number = raw_input('input type you number:')
input type you number:3
>>> print info.get(number,'error')
third
>>> number = raw_input('input type you number:')
input type you number:4
>>> print info.get(number,'error')
error

希望本文所述对大家的Python程序设计有所帮助。
