输出结果：

111.172.249.86->1111.172.249.84->2111.172.249.85->1 |
注释：python字段的setdefault用法为获取信息，如果获取不到的时候就按照他的参数设置该值

>>> a={} >>> a['key']='123'>>> print (a) {'key': '123'} >>> print (a.setdefault('key','456'))#显示a这个字典的'key'值的内容,因为字典有，所以不会去设置它 123>>> print (a.setdefault('key1','456'))#显示a这个字典的'key1'值的内容，因为字典没有，所以设置为456了 456>>> a {'key1': '456', 'key': '123'} |
希望本文所述对大家的Python程序设计有所帮助。
