如何在python中从字符串列表中删除多个不需要的字符？

Question

我有以下输入字符串：

text='''Although never is often better than *right* now.

If the implementation is hard to explain, it's a bad idea.

If the implementation is easy to explain, it may be a good idea.

Namespaces are one honking great idea -- let's do more of those!'''

到目前为止，我已经将text字符串拆分为list，如下所示：

^{pr2}$

现在，我想使用strip函数从上面的列表中删除不需要的字符，比如\n\n和{}。在

你能帮我一下吗？？在

使用re模块，^{}函数将允许您这样做。 我们需要用单个的\n替换multilpe\n出现，并删除 字符串

import re

code='''Although never is often better than right now.

If the implementation is hard to explain, it's a bad idea.

If the implementation is easy to explain, it may be a good idea.

Namespaces are one honking great idea   let's do more of those!'''


result = re.sub('\n{2,}', '\n', code)
result = re.sub('   ', ' ', result)

print(result)

然后分割你的文本。在
