Question

我想从电子邮件中过滤掉自动文本。这些是这样的行：

如果您收到此电子邮件错误，请发送回给我们立即 \ r \ n 并将其永久删除，请勿使用，复制或披露电子邮件或任何附件的内容。

为此，我创建了这些句子的列表，并将其过滤为：

def remove_redundant_text(body):
    for i in filter_lists.body_filter_list:
        body = body.replace(i, "")
    return body

但是，这是行不通的，因为换行符和其他转义字符会随机出现在文本中，例如示例中的 \ r \ n 。如何使.replace()忽略这些？

让我给出输入和所需的输出示例。

Answer 1

我尝试了以下代码，它可以按预期工作。

完整代码：

body = (
    "If you receive this email in error, please send it back "
    "to us immediately \r\n and permanently delete it and do not "
    "use, copy or disclose the content of the email or any attachment."
)


def remove_redundant_text(body):
    for i in ["\n", "\r"]:
        body = body.replace(i, "")
    return body

print(remove_redundant_text(body))

输出：

>>> python3 test.py 
If you receive this email in error, please send it back to us immediately  and permanently delete it and do not use, copy or disclose the content of the email or any attachment.

一个更有效的解决方案是正则表达式。您可以使用re.sub。当你可以在下面看到，您可以使用正则表达式。

代码：

import re

body = (
    "If you receive this email in error, please send it back "
    "to us immediately \r\n and permanently delete it and do not "
    "use, copy or disclose the content of the email or any attachment."
)

print(re.sub("\r|\n", "", body))

输出：

>>> python3 test.py 
If you receive this email in error, please send it back to us immediately  and permanently delete it and do not use, copy or disclose the content of the email or any attachment.
