從我的電子郵件正文中提取日期（已經有一個代碼可以提取所有電子郵件的正文）

Question

編碼知識非常有限，但我有這段代碼可以提取我的電子郵件正文，我想把它放到只提取電子郵件正文中的日期的地方。 沒有嘗試太多，因為我不知道如何處理它。 '''

# if the email message is multipart
            if msg.is_multipart():
                # iterate over email parts
                for part in msg.walk():
                    # extract content type of email
                    content_type = part.get_content_type()
                    content_disposition = str(part.get("Content-Disposition"))
                    try:
                        # get the email body
                        body = part.get_payload(decode=True).decode()
                    except:
                        pass
                    if content_type == "text/plain" and "attachment" not in content_disposition:
                        # print text/plain emails and skip attachments
                        print(body)
                    elif "attachment" in content_disposition:
                        # download attachment
                        filename = part.get_filename()
                        if filename:
                            folder_name = clean(subject)
                            if not os.path.isdir(folder_name):
                                # make a folder for this email (named after the subject)
                                os.mkdir(folder_name)
                            filepath = os.path.join(folder_name, filename)
                            # download attachment and save it
                            open(filepath, "wb").write(part.get_payload(decode=True))
            else:
                # extract content type of email
                content_type = msg.get_content_type()
                # get the email body
                body = msg.get_payload(decode=True).decode()
                if content_type == "text/plain":
                    # print only text email parts
                    print(body)
            if content_type == "text/html":
                # if it's HTML, create a new HTML file and open it in browser
                folder_name = clean(subject)
                if not os.path.isdir(folder_name):
                    # make a folder for this email (named after the subject)
                    os.mkdir(folder_name)
                filename = "index.html"
                filepath = os.path.join(folder_name, filename)

整個代碼更長，但我假設解決方案只能通過調整這些單元格來實現。 任何幫助表示贊賞！

您將需要為此使用正則表達式。
