python 解析日志文件：在不同的行中找到两个特定的字符串并连接到一个并写入另一个文件！ 避免空行

Question

我的日志喜欢这个文件

我需要看起来像什么：

行：5，错误：帐户维度的成员不是基本级别。|>>>>>>A1399
行：6，错误：没有这样的成员|>>>>>>401700

我需要解析一个日志文件，只找到感兴趣的错误并将它们写入另一个文件。 下面是使用两个标签（ 'Line:','>>>>>>' ）的代码我需要获取这两个标签之后的所有字符串并连接到一个新行中。
我得到很多空行，两个标签在不同的行中。
先感谢您！

def main():
    fo = open("C:\\Users\\yannis\\py_script\\1198.log", "r", encoding="ISO-8859-1")
    ofile = open("C:\\Users\\yannis\\py_script\\out.txt",'a', newline='')
    member = ""
    erro = ""

    f1 = fo.readlines()
    for x in f1:
        erro = (x[x.find('Line:'):])
        member = (x[x.find('>>>>>>'):])

        linha = (erro + member)
        print(linha)
        ofile.write(linha)
        continue




    fo.close()
    ofile.close()



main()

def log_parser(path):
    with open(path, 'r', encoding='utf-8') as f:
        temp = dict()
        for index, line in enumerate(f.readlines()):
            _line_except = line[:-1]
            [day, time, level, something, *arg] = _line_except.split(' ')

            if 'Error:' in arg and 'Line:' in arg:
                temp = {
                    "log_info": " ".join([day, time, level, something]),
                    "log_str": " ".join(arg)
                }
            elif len(arg) == 1:
                print("{log_info} {log_str} || {other_args}".format(
                    log_info=temp['log_info'],
                    log_str=temp['log_str'],
                    other_args=arg[0])
                )
            else:
                continue


if __name__ == '__main__':
    log_parser("log.txt")

你会得到..

当您不在日志文件中写入“>>>>12345”时，将会发生错误。 -> 它将在临时字符串之前被丢弃。 你应该认出它。
