为什么我的python控制台日志包含换行而不是换行？

Question

我有一个python3服务，它读取传感器并通过MQTT发送值（参见pitelemetry）。它是作为一个Python模块编写的，主程序在它们自己的文件中包含一系列类。运行时，为每个传感器生成一个线程

使用此设置，当我以交互方式运行时，会看到以下控制台日志：

       [2019-12-23 15:53:49,628 - pitelemetry.mqtt/Thread-2 - DEBUG] - Connected to broker: mqtt.agdon.net

如您所见，所有的启动都正常，但是当较低级别的类开始记录时，没有换行符，只有换行符

知道为什么吗
