为什么我的日志被打印了两次

Question

为什么我的日志被打印了两次 我有三个python文件 当我调用test2时： 我的日志已经打印了两次了

2018-06-29 20:41:36,466 - test - INFO - 2222222222222222222
2018-06-29 20:41:36,466 - test - INFO - 2222222222222222222

我没有把AAA方法称为我的指纹。你知道吗

手柄_对数.py你知道吗

# sys.path.append('/data1/test/app_sem')

b = BBBB()
a = AAAA()
# a.my_print()

# b.my_print_b()

结果：

2018-06-29 20:41:36,466 - test - INFO - 2222222222222222222
2018-06-29 20:41:36,466 - test - INFO - 2222222222222222222

为什么同一行打印两次？你知道吗

Answer 1

您的所有记录器都具有相同的名称“test”，因此当您向“test”发送日志消息时，所有记录器都会做出反应。你知道吗

为了能够拥有多个记录器，请确保为它们提供不同的名称，例如，使用“path”变量。你知道吗

或者例如：

class Logger(object):
def __init__(self, path='test',title=None):
    self.logger = logging.getLogger(path + title)
    [...]
