logging.info不会显示在控制台上，但会发出警告和错误提示 [英] logging.info doesn't show up on console but warn and error do

问题描述

当我使用logging.info记录事件时，该事件不会出现在Python终端中.

When I log an event with logging.info, it doesn't appear in the Python terminal.

import logging
logging.info('I am info')  # no output

相反，用logging.warn记录的事件确实出现在终端中.

In contrast, events logged with logging.warn do appear in the terminal.

import logging
logging.warn('I am warning')  # outputs "I am warning"

是否可以更改环境级别以将logging.info打印到控制台?我想避免在每个Python文件中进行更改.

Is there a environment level change I can to make logging.info print to the console? I want to avoid making changes in each Python file.

推荐答案

root logger始终默认为WARNING级别.尝试致电

The root logger always defaults to WARNING level. Try calling

logging.getLogger().setLevel(logging.INFO)

你应该没事.
