如何使用logger.warning ()将f.write调整为导出

Question

我有一个来自库的代码的和平，它会发出警告：

   report_methods = {
        "missing_bus_indices": diag_report.report_missing_bus_indices,
        "disconnected_elements": diag_report.report_disconnected_elements,
        "different_voltage_levels_connected": diag_report.report_different_voltage_levels_connected,
        "impedance_values_close_to_zero": diag_report.report_impedance_values_close_to_zero,
        "nominal_voltages_dont_match": diag_report.report_nominal_voltages_dont_match,
        "invalid_values": diag_report.report_invalid_values,
        "overload": diag_report.report_overload,
        "multiple_voltage_controlling_elements_per_bus": diag_report.report_multiple_voltage_controlling_elements_per_bus,
        "wrong_switch_configuration": diag_report.report_wrong_switch_configuration,
        "no_ext_grid": diag_report.report_no_ext_grid,
        "wrong_reference_system": diag_report.report_wrong_reference_system,
        "deviation_from_std_type": diag_report.report_deviation_from_std_type,
        "numba_comparison": diag_report.report_numba_comparison,
        "parallel_switches": diag_report.report_parallel_switches
    }
    # separator between log messages
    log_message_sep = ("\n --------\n")

    logger.warning("\n\n_____________ PANDAPOWER DIAGNOSTIC TOOL _____________ \n")
    for key in report_methods:
        if (key in diag_results) :
            report_methods[key]()
            logger.warning(log_message_sep)

    logger.warning("_____________ END OF PANDAPOWER DIAGNOSTIC _____________ ")

下面是我在python控制台中得到的结果：

我想用我尝试过的f.write将这个内容写入txt文件：

    for key in report_methods:
        if (key in diag_results) :
            if not report_methods[key]() is None :
                f.write(report_methods[key]())
                f.write(log_message_sep)

但是f.write(report_methods[key]())无法正常工作: txt文件不包含所需的信息。

我该怎么做？

Answer 1

我认为您所需要做的就是在日志配置中添加一个FileHandler，它将把所有日志消息(包括其他库编写的日志消息)写入指定的文件中(除非其他库为自己的记录器定义了另一组处理程序，这是不太可能的，因为这将是一种糟糕的实践，而且在您提供的链接中也不是这样)。

我不知道您的日志配置是什么样子(如果您设置了一个)，但是下面是一个示例：

file_handler = logging.FileHandler('your\\log\\path_here.txt', 'w', delay=False)
file_handler.setLevel(logging.INFO)    # this only allows anything up to the "info" level to be written to your file

logging.basicConfig(
    level=logging.DEBUG,               # this allows all log messages to appear in the console
    format='{asctime} {lineno:<3} {levelname} {funcName}: {message}',
    datefmt='%m/%d/%y | %I:%M:%S%p',
    style='{',
    handlers=(file_handler, logging.StreamHandler())   # this adds our FileHandler and a StreamHandler (for console logs)
)

请注意，可以为每个处理程序指定不同的日志记录级别。在本例中，我设置了DEBUG的全局级别(因此几乎允许任何日志消息)，但对于FileHandler，我将级别限制为INFO，但如果愿意，可以将其限制为WARNING。如果您不熟悉以下是可用的日志记录级别 (每个级别都允许它之上的每个级别)。

我百分之九十五肯定这就是你所需要的。
