在换行符上拆分python中的字符串[重复]答案

【问题标题】：split a string in python on linebreaks [duplicate]在换行符上拆分python中的字符串[重复]
【发布时间】：2013-08-30 19:02:00
【问题描述】：

我有一个包含一系列时间和活动的元组。所以，它会类似于这样：

('08:01: Woke Up\n08:05: Took Shower\n08:20: Ate Breakfast\n08:45: Left for work', )

我需要能够像这样进行每个活动并单独显示：

8:01 Woke Up
8:05 Took Shower
8:20 Ate Breakfast
8:45 Left for work

谁能给我一个关于在 python 中最好/最简单的方法的建议？谢谢。

【解决方案1】：

您已经在元素中有换行符，所以只需打印：

>>> tup = ('08:01: Woke Up\n08:05: Took Shower\n08:20: Ate Breakfast\n08:45: Left for work',)
>>> print tup[0]
08:01: Woke Up
08:05: Took Shower
08:20: Ate Breakfast
08:45: Left for work

您可以使用str.splitlines() 将字符串拆分为单独的元素：

>>> tup[0].splitlines()
['08:01: Woke Up', '08:05: Took Shower', '08:20: Ate Breakfast', '08:45: Left for work']
>>> for line in tup[0].splitlines():
...     print line
... 
08:01: Woke Up
08:05: Took Shower
08:20: Ate Breakfast
08:45: Left for work

如果您需要将时间和活动作为单独的字符串，请拆分字符串': ' 上的每一行：

>>> for line in tup[0].splitlines():
...     time, activity = line.split(': ', 1)
...     print time, activity
... 
08:01 Woke Up
08:05 Took Shower
08:20 Ate Breakfast
08:45 Left for work

很好的答案。如果你想把每一行分成一个时间和一个活动，你可以做line.split(None, 1)或line.partition(' ')。
@abarnert：实际上是在': ' 上拆分；现在我的输出与问题样本匹配。
非常详细和准确的答案。谢谢，也感谢其他回复。
@MartijnPieters：是的，这行得通，但我不确定它是否更具可读性；您必须考虑第一个冒号不算数的事实，因为它后面没有空格……

【解决方案2】：

你有没有想过字典？您可以将时间信息存储为键，将活动存储为值，如下所示：

dictionary = {}
dictionary['8:01'] = 'Woke Up'
dictionary['8:05'] = 'Took Shower'
dictionary['8:20'] = 'Ate Breakfast'
dictionary['8:45'] = 'Left for work'

然后以您可以简单的格式打印：

for k in dictionary:
    print k + ' ' + dictionary[k]

【解决方案3】：

你似乎没有一个元组，你有一个字符串，如果你打印，它会准确地给你你想要的。

假设您有一个元组列表（我假设这就是您的意思），您应该这样做：

input = [("8:01", "Woke Up"), ("8:05", "Took shower"), ("8:20", "Ate Breakfast")]
for time, description in input:
  print time, description

>>> t = ('08:01: Woke Up\n08:05: Took Shower\n08:20: Ate Breakfast\n08:45: Left for work', )
>>> for elem in t:
...     print elem.split('\n')
...
['08:01: Woke Up', '08:05: Took Shower', '08:20: Ate Breakfast', '08:45: Left fo
r work']
>>> for elem in t:
...     for activity in elem.split('\n'):
...             print activity
...
08:01: Woke Up
08:05: Took Shower
08:20: Ate Breakfast
08:45: Left for work
>>> for elem in t:
...     print elem
...
08:01: Woke Up
08:05: Took Shower
08:20: Ate Breakfast
08:45: Left for work
