Python子字符串函数从字符串中获取多个数据块

Question

我有一个数据字符串，其中包含一些文本数据和一些json数据，现在我希望将此文本的所有json事件提取到单个变量中。 以下是原始数据

    },

        }
    }
}--fd709ff560be6440aafc1c097a8b6c8a--

下面是python代码

def find_between( myrawData, first, last ):
    try:
        start = myrawData.index( first ) + len( first )
        end = myrawData.index( last, start )
        return myrawData[start:end]
    except ValueError:
        return ""

def find_between_r( myrawData, first, last ):
    try:
        start = myrawData.rindex( first ) + len( first )
        end = myrawData.rindex( last, start )
        return myrawData[start:end]
    except ValueError:
        return ""


if __name__ == "__main__":
    first_rdata=find_between_r(myVarStr,'X-Ua-Compatible: IE=edge','--')
    print(first_rdata)

我希望得到以下输出，其中包含来自字符串的两个json数据，因为合并一个字符串也可以
