Python：遍历包含换行符的字符串

Question

我有一个由换行符分隔的字符串，我需要单独处理每一行。我想我可以使用for循环来迭代。但是，这将单独打印每个字符。

示例：

convo = "Bob: Hello \n Sandy: How are you? \n Bob: Confused by a python problem"

for line in convo:
    print(line)

>>> B
>>> o
>>> b
>>> :

最好的办法是什么？

Answer 1

您可以使用str.splitlines：

>>> convo = "Bob: Hello \n Sandy: How are you? \n Bob: Confused by a python problem"
>>> for line in convo.splitlines():
...     print(line)
...
Bob: Hello
 Sandy: How are you?
 Bob: Confused by a python problem
>>>

从docs：

str.splitlines([keepends])

Return a list of the lines in the string, breaking at line boundaries. This method uses the universal newlines approach to splitting lines. Line breaks are not included in the resulting list unless keepends is given and true.
