有没有办法在Python中的每个']'之后添加新行？

Question

我最初有一个包含BBCode的字符串，我想在其中对其进行更好的格式化，使其可读

我有点像

每个']'后面都有一条新的线

我试图调整re.sub("[\(\[].*?[\)\]]", "", str(x))以满足我的需要，但它只是删除了其中的所有内容。（我不知道正则表达式是如何工作的）

我该怎么办

Answer 1

不需要正则表达式，只需使用简单的str.replace()函数即可

x = x.replace(']', ']\n')

Answer 2

这实际上取决于您希望输出的外观

我将您的输出解释为希望在每个url=标记后面有一个换行符，这需要以下正则表达式：

output = re.sub(r"(\[url.*?\])", r"\1\n", input)

括号()形成一个捕获组，该捕获组在replace语句中用作\1，因为它是第一个未命名的捕获组

您可以根据自己的意愿更改正则表达式，但只需将想要保留的内容保留在捕获组中即可

如果你想尝试正则表达式，你可以使用https://regexr.com/，这是一个神奇的资源，当你摆弄正则表达式的时候
