import random
userKeywords = {"hi","hello","wassup","what'sup","greetings","sup","henlo","que onda","hola","hey","waddup"}

machineResponses = list({"hello", "Hello there, I am a bot", "greetings from inside this computer"})

def machineAnswer(message):
    if message in userKeywords:
        return random.choice(machineResponses)

基本上是7bit和3之间的任何东西。

我已经尝试了以下正则数据没有成功：正则表达式＃1：Content-Type: text/plain; charsetUTF-8 Content-Transfer-Encoding: 7bit "test" ---

我以为我能够使用捕获群来获取内容，但我遇到了各种各样的问题。我正在使用MacOS终端和Content-Type: text/plain;(.*)(\n\n)(.*)---。

Answer 1

在PCRE中，.不包含多行。您需要使用单行修饰符让.包含它们。尝试将(?s)添加到正则表达式中，如下所示：

(?s)Content-Type: text/plain;(.*)(\n\n)(.*)---

或者你可以使用：

Content-Type: text/plain; charsetUTF-8 Content-Transfer-Encoding: 7bit\s*([\s\S]*?)-{3}

正则表达式获取原始RFC 822格式的电子邮件的正文
