【python入门到放弃】字典元素的循环打印

#定义一个字典
dic = {'name':'wusan','pwd':27,'sex':'女'}

#循环打印出默认的字典元素，实际为key值
for item in dic:
    print(item)

#循环打印出字典中的key值
for item in dic.keys():
    print(item)

#循环打印出字典中的value值    

for item in dic.values():
    print(item)

#循环打印出字典中的键值对
for item in dic.items():
    print(item)

#循环分别打印出字典中的key值和value值
for k,v in dic.items():
    print(k)
    print(v)
