我应该如何假设三种贵重物品并在此代码块中打印出来

问题描述

    marks=[
     [120,0],[100,20,20],[80,[60,40,[40,40],[20,60],80],100],[0,120]
]



for raw in marks:
     for item in raw:
          pass_mark=item
          defer_mark=item
          fail_mark=item
          print(pass_mark,defer_mark,fail_mark)

解决方法

使用索引

for raw in marks:
    pass_mark=raw[0]
    defer_mark=raw[1]
    fail_mark=raw[2]
    print(pass_mark,defer_mark,fail_mark)

如果您需要短代码，可以使用以下代码：

for raw in marks:
   print(*raw)   # pass list as args

,

方法1-

for raw in marks:
    print(raw[0],raw[1],raw[2])

方法2-

for i,value in enumerate(marks):
    print(*value)

方法3-

for raw in marks:
    print(','.join(map(str,raw)))
