推荐答案

来自文档

原始字符串由三引号(")分隔，不包含 转义，并且可以包含换行符和任何其他字符

A raw string is delimited by a triple quote ("""), contains no escaping and can contain newlines and any other character

您需要在换行符中使用标准字符串

You would need to use a standard string with newlines

" ...\n \$eq \n ... "

或者您可以使用文字表示形式

or you could use the literal representation

""" ... ${'$'}eq ... "
