python基础内容

1 使用方法dict_a.items()和dict_a.values()

[root@ops-pdc-02 python]# more dict_aa.py 

dict_a = {'k1':'v1','k2':'v2','k3':'v3'}
for k,v in dict_a.items():
    print 'key is %s,value is %s' %(k,v)
print '------------------'
for v in dict_a.values():
    print 'values is %s' %v

[root@ops-pdc-02 python]# python dict_aa.py   
key is k3,value is v3
key is k2,value is v2
key is k1,value is v1
------------------
values is v3

values is v2

values is v1

---------------------------
