logging: try to avoid using ANSI color codes when not logging to a terminal Color on the console is nice, but it is annoying to get these codes when for example redirecting to a file. The formatter doesn't know exactly where the message will be used - it is fully configurable. In the default configuration, the messages are passed to a StreamHandler to sys.stderr . As an approximate optmization, hardcode the color formatters to only emit color formatting if logging to something that isatty.
