python学习笔记之--dict 字典

dict = {3:{301:[1,80],302:[1,80],303:[2,90],304:[2,90]},
        4:{401:[1,80],402:[1,80],403:[2,90],404:[2,90]},
        5:{501:[1,80],502:[1,80],503:[2,90],504:[2,90]}
       }
for value in dict.values(): 
# value的名字可以自行另取
# dict是要遍历的字典的名称
# .values():是固定的用法
    print(values)
