如果正则表达式匹配，则向消息添加文件路径

Question

我有以下 Python 脚本（摘录如下），它读取 E:\Data\Production 目录下的所有日志文件并查找某些正则表达式匹配项。errors, tr, warnings = [], [], []rootdir = 'E:\\Data\\Production'for folder, dirs, files in os.walk(rootdir):    for file in files:        if file.endswith('.log'):            fullpath = os.path.join(folder, file)            with open(fullpath, 'r') as f:                for line in f:                    for match in re.finditer(r'.*' + daysdate + '(?!.*[->OK].*).*[Ee]rror.*', line):                        errors.append(match.group(0))                    for match in re.finditer(r'.*' + daysdate + '.*(?!.*deployed)(?!.*complete.*)(?!.*There are no.*)(?!.*disabled.*).*TR\d{4}.*', line):                        warnings.append(match.group(0))                    for match in re.finditer(r'.*' + daysdate + '.*(?!.*deployed)(?!.*[->OK])(?!.*complete.*)(?!.*There are no.*)(?!.*disabled.*).*TR\d{4}.*', line):                        tr.append(match.group(0))if errors == []:    errors.append("No errors found.")[...]sendmail():    "Errors:\n\n%s\n" % "\n".join(map(str, errors)) +    "\Faulty:\n\n%s\n" % "\n".join(map(str, tr)) +    "\Warnings:\n\n%s\n" % "\n".join(map(str, warnings))sendmail()这个的输出是：Errors:No errors found.Faulty:<the entire line containing the matched regex>Warnings:No errors found.我想要做的是添加发现错误的日志文件的完整路径，因此它会改为：Errors:No errors found.Faulty:<the entire line containing the matched regex>Error found in file: E:\Data\Production\qwer\asdf\zxcv.logWarnings:No warnings found.我假设我需要以某种方式附加 fullpath 变量，但我不知道如何实现它。

我相信你需要。

for match in re.finditer(r'.*' + daysdate + '.*(?!.*deployed)(?!.*[->OK])(?!.*complete.*)(?!.*There are no.*)(?!.*disabled.*).*TR\d{4}.*', line):
    tr.append(match.group(0) + "\n{0}".format(fullpath))
