我有一个名为player的嵌套列表,如下所示：

players = [["PlayerA","10","20"],["PlayerB","15","30"],["PlayerC","30"] ]

我希望能够使用输入语句按播放器名称(PlayerA,PlayerB等)进行搜索,如果搜索与项目匹配,则打印出整个项目.我将如何做到这一点,我正在尝试学习不同的方法.

search = input("Please enter the players name")
for item in players:
  if item == search:
     print(item)
  else:
     print("item not found")

当我执行上述操作时,它会保留未找到的打印项目.

提前谢谢了.

解决方法

是的只是让你像这样的代码：

players = [["PlayerA","30"] ]
search = input("Please enter the players name: ")

result = [player for player in players if player[0] == search]

if result == []:
    print("item not found")
else:
    print(result)
