Question

Python 2.7

我目前正在使用多行代码进行日志记录，如下所示：

timestr = time.strftime("%Y%m%d_%H%M%S")
print timestr
logging.basicConfig(level=logging.DEBUG,
                    format='%(asctime)s %(name)-12s %(levelname)-8s %(message)s',
                    datefmt='%m-%d %H:%M',
                    filename='D://my_code_3/logging/'+timestr+'_XFR.log',
                    filemode='w')
#define a Handler which writes INFO messages or higher to the sys.stderr
console = logging.StreamHandler()
console.setLevel(logging.INFO)
#set a format which is simpler for console use
formatter = logging.Formatter('%(name)-12s: %(levelname)-8s %(message)s')
#tell the handler to use this format
console.setFormatter(formatter)
#add the handler to the root logger
logging.getLogger('').addHandler(console)

name = raw_input("Please enter your name.")
print 'Hi ', name, 'Please go ahead and transfer files - Press Enter'
print
#####
now = datetime.datetime.now()
logging.debug ('File was transferred by:')
logging.debug(name)
logging.debug('The transfer took palce on:')
logging.info(now.strftime("%Y-%m-%d %H:%M"))

我喜欢使用类似于以下内容的单行：

logging.debug (('File was transferred by:'), name)

但这种语法错了。请帮我解决这个问题。 /或者，请建议我另一种将数据流式传输到日志文件/控制台和日志文件的方法。

非常感谢。 +

Answer 1

# Use python3 f-string, it has better syntax
logging.debug(f'File was transferred by: {name}')

Answer 2

您可以使用字符串格式

logging.debug ('File was transferred by: {}'.format(name))

那清洁易读

或logging.debug ('File was transferred by: %s' % name)

您可以阅读更多相关信息Python format string syntax docs

logging.debug的多个参数
