我有很多清单
1 2 3 | ['it'] ['was'] ['annoying'] |
我想让上面看起来像
1 | ['it', 'was', 'annoying'] |
我怎样才能做到？
只需添加它们：
1 | ['it'] + ['was'] + ['annoying'] |
您应该阅读python教程来学习这样的基本信息。
1 2 3 | import itertools ab = itertools.chain(['it'], ['was'], ['annoying']) list(ab) |
只是另一种方法……
1 2 3 4 5 6 7 8 | a = ['it'] b = ['was'] c = ['annoying'] a.extend(b) a.extend(c) # a now equals ['it', 'was', 'annoying'] |
