python 学习 字典

 类似map

cc = {'magic':'1','saber':'2','master':'3','archer':'4',}

添加键-值对

cc['newKey']=newValue

删除键-值对

del cc['key']

循环

#单独循环key
for key in cc:
for key ind cc.keys():
#单独循环value
for value in cc.values():
#排序
for name in sorted(cc.keys()):
#去重
for val in set(cc.values()):

for key, value in cc:
    print(key)
    print(value)
