Question

added = ['hypr1005.ops.colo.cmp.com,web1234.ads.colo.cmp.com,876543,4']

上面的变量是一个列表，它包含单个值，用逗号分隔，我只想用逗号分割值并创建一个看起来像

的列表

added = ['hypr1005.ops.colo.cmp.com','web1234.ads.colo.cmp.com','876543','4']

words = added.split(',')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'list' object has no attribute 'split'

猜猜拆分仅适用于不在列表中的字符串，所以我该怎么做？

Answer 1

调用列表第一项（split）的added[0]方法：

>>> added = ['hypr1005.ops.colo.cmp.com,web1234.ads.colo.cmp.com,876543,4']
>>> added = added[0].split(',')
>>> added
['hypr1005.ops.colo.cmp.com', 'web1234.ads.colo.cmp.com', '876543', '4']

Answer 2

为了使用split，它应该是一个字符串。

>>> added = "'hypr1005.ops.colo.cmp.com','web1234.ads.colo.cmp.com','876543','4'"
>>> words = added.split(',')
>>> words
["'hypr1005.ops.colo.cmp.com'", "'web1234.ads.colo.cmp.com'", "'876543'", "'4'"]
>>>
