Python正則表達式re.compile搜索失敗

我使用https://regex101.com/#python來構建regx搜索的以下模式。雖然它在構建器網站中工作正常，但它似乎在我的python腳本中失敗。回溯表明AttributeError: 'NoneType' object has no attribute 'group'Python正則表達式re.compile搜索失敗

在您的正則表達式替換\\與\。需要 –

沒了，這並不工作，並停止在文字上的''\ nphone：'或'\ nRegDate：' – iNoob

'\ nphone：'是不是真的'\ nphone：'，它是一個換行符之後'電話： '。嘗試'print（raw [0]）'看看你自己。 – Chris

在第二種方式表達，Address(.*?)(?=\\nRegDate:)，你似乎想.匹配任何字符，包括換行，這是不正常的意義。

試試這個：

address_t = re.compile(pattern_string, re.DOTALL)

羅布現貨，感謝您花時間查看問題和可用數據。 – iNoob

不客氣，但它花了我比我們更長的時間，因爲您的測試程序實際上並不是您的測試程序。我必須修復兩個語法錯誤才能運行。將來，請**複製粘貼**（不要重新鍵入或總結）您的整個**（例如，不跳過「導入」）短程序，以顯示錯誤。這是我實際測試的程序：http：//ideone.com/dYYJHc。有關提問的更多提示，請參見[問]和[mcve]。 –
