如何在python中使用re.findall提取日期及其后的所有數據

Question

我有一個字符串，我希望使用正則表達式從字符串中分離出一些信息。

我遇到的以下代碼有兩個我知道的問題：1）由於我不確定我是否理解（也許已編譯的正則表達式查詢未完成），因此無法捕獲日期“ 20120623”我期望它做什么？），以及2）我用於指定表達式結束方式的當前regex表達式不適用於字符串中的最后一個匹配項。

我可能會修改該問題的標題，具體取決於最終解決的問題/解決方案是什么。

當前代碼：

Answer 1

嘗試使用正則表達式：

(\d{8}\s)10\.3\s-84\.8\$(.*?)(?=\d{8}|$)

您當前的正則表達式由於匹配重疊而阻止了連續匹配； 我通過使用正寬度(?= ... ) （零寬度斷言(?= ... )消除了此問題。

另外，我逃脫了你的任期。 如果要用作文字點，則應將其轉義。

Answer 2

它看起來不像您的正則表達式將匹配您的字符串。

您的正則表達式將查找8位數字，后跟“ 10.3 -84.8 $”，然后捕獲所有內容，然后再捕獲8位數字。 但是，看起來您的字符串在其他任何地方都不具有這8位數字。
