Python 如何格式化日志，使其以列形式打印？

我有一个项目，其中不同的线程和函数使用不同的日志级别登录到控制台中相同的

StreamHandler（）

我的日志格式化为：

streamformatter = logging.Formatter(fmt='%(levelname)s:\t%(threadName)s:\t%(funcName)s:\t\t%(message)s', datefmt='%H:%M:%S')

这使得我的日志在默认情况下看起来像这样乱七八糟，在什么时候调用什么函数以及从哪个线程调用函数都不容易看到

每个令牌的宽度可以在
streamformatter
中指定，以这种方式生成固定冒号的日志输出：

streamformatter = logging.Formatter(fmt='%(levelname)-10s:  %(threadName)-20s: %(funcName)-20s:  %(message)s', datefmt='%H:%M:%S')
